Smaller Than a Pushpin, More Powerful Than a PC

AN FRANCISCO, Feb. 6 - In a new volley in the battle for digital home
entertainment, I.B.M., Sony and Toshiba will announce details Monday of
their newest microprocessor design, known as Cell, which is expected to
offer faster computing performance than microprocessors from Intel and
Advanced Micro Devices.
Anticipation of the announcement, to be made at an industry conference here,
has touched off widespread industry speculation over the impact of the new
chip technology, which promises to enhance video gaming and digital home
entertainment.
Sony plans to use the new Cell in its PlayStation 3, likely to be introduced
in 2006, and Toshiba plans to use the chip in advanced high-definition
televisions, also to be introduced next year.
However, many industry executives and analysts say that Cell's impact may
ultimately be much broader, staving off the PC industry's efforts to
dominate the digital living room and at the same time creating a new digital
computing ecosystem that includes Hollywood, the living room and
high-performance scientific and engineering markets.
"There is a new game in town, and it will revive an industry that has been
kind of sleepy for the last few years," said Richard Doherty, a computer
industry analyst and president of Envisioneering, a market research company
in Seaford, N.Y.
The Cell's introduction also comes at a time when the computer industry has
largely given up investing in fundamentally new processor designs and has
instead chosen to use the additional space available on the newest
generation of chips to place multiple processors and thus add performance.
The Cell chip, computer experts said, could have a theoretical peak
performance of 256 billion mathematical operations per second. With that
much processing power, the chip would have placed among the top 500
supercomputers on a list maintained by scientists at the University of
Mannheim and the University of Tennessee as recently as June 2002.
"This is extremely impressive," said Kevin Krewell, editor in chief of
Microprocessor Report, an industry technical publication, "and it proves
that architectural innovation isn't dead."
Several computer industry executives warned, however, that despite the
Cell's impressive specifications, success is not guaranteed for any new
design in the computer industry. For example, Intel and Hewlett-Packard have
spent more than a decade and hundreds of millions of dollars on the Itanium
and the chip has yet to find a receptive market.
The Cell has a modular design based on a slightly less powerful I.B.M.
processor that is currently in G5 64-bit desktop computers from Apple
Computer. Additionally, the Cell architecture is distinguished by the fact
that it controls an array of eight additional processors that the design
team refers to as synergistic processing elements, or S.P.E.'s. Each of the
S.P.E.'s is a 128-bit processor in its own right.
The Cell has some components that in the lab switch at 5.6 GHz, and several
people familiar with the design said that it was both more flexible than is
generally understood and that it has been designed with high bandwidth
communications, such as high-speed data links to homes, in mind.
"Cell has been optimized for broadband-rich applications," said Jim Kahle,
I.B.M.'s director of technology at the Design Center for Cell Technology,
the headquarters in Austin, Tex., for the I.B.M., Sony and Toshiba
partnership.
He said that I.B.M. had refined a technology also being developed by Intel
called "virtualization," which is designed to isolate applications from one
another. Originally used in mainframe computing applications, the technology
is now being exploited by consumer electronics designers to run demanding
applications like video decompression and decryption simultaneously.
One significant risk for Sony and I.B.M. is that the Sony PlayStation 3 game
machine is likely to be introduced later than the next generation of Xbox
from Microsoft. The PlayStation 2 beat the Xbox to market and Microsoft was
never able to catch up, meaning that it lost hundreds of millions of dollars
on its bet on the video game market.
In its next version of the Xbox, Microsoft plans to shift from using Pentium
chips from Intel to a PowerPC microprocessor from I.B.M. The chip will have
two PowerPC processor cores, but it will not be as radically new as the
I.B.M. Cell design that Sony plans to use, said one executive who is
familiar with the Microsoft project.
That will make for a fascinating rivalry: Sony is betting that its computer
horsepower advantage will be large enough to give it a quality advance over
Microsoft, even if it arrives late.
"Our goal with the Cell is to be an order of magnitude faster," said Lisa
Su, an I.B.M. executive in charge of technology development and licenses.
Many industry executives believe that because of its low cost, the Cell is a
harbinger of a fundamentally new computing era that will push increasingly
into consumer applications.
"I think it will aid in some of the convergence between consumer and
corporate I.T. and this will accelerate amazingly from the consumer side,"
said Andrew Heller, a former I.B.M. processor designer who is now chairman
of Heller & Associates, a consulting firm in Austin, Tex.
One area of wide speculation is whether Apple might become a partner in the
Cell alliance in the future. Apple is already the largest customer for the
PowerPC chip, and it would be simple for the company to take advantage of
the Cell design. Several people familiar with Apple's strategy, however,
said that the computer maker had yet to be convinced that the Cell
technology could provide a significant performance advantage.

Core, Delivers More Than 10 Times the Performance of the Latest PC
Processors
SAN FRANCISCO--(BUSINESS WIRE)--Feb. 7, 2005-- At the International Solid
State Circuits Conference (ISSCC) today, IBM, Sony Corporation, Sony
Computer Entertainment Inc. (Sony and Sony Computer Entertainment
collectively referred to as Sony Group) and Toshiba Corporation (Toshiba)
for the first time disclosed in detail the breakthrough multi-core
architectural design - featuring supercomputer-like floating point
performance with observed clock speeds greater than 4 GHz - of their jointly
developed microprocessor code-named Cell.
Source: IBM
· View multimedia news release
A team of IBM, Sony Group and Toshiba engineers has collaborated on
development of the Cell microprocessor at a joint design center established
in Austin, Texas, since March 2001. The prototype chip is 221 mm(2),
integrates 234 million transistors, and is fabricated with 90 nanometer SOI
technology.
Cell's breakthrough multi-core architecture and ultra high-speed
communications capabilities deliver vastly improved, real-time response for

performance of the latest PC processors.
Effectively a "supercomputer on a chip" incorporating advanced
multi-processing technologies used in IBM's sophisticated servers, Sony
Group's computer entertainment systems and Toshiba's advanced semiconductor
technology, Cell will become the broadband processor used for industrial
applications to the new digital home.
Another advantage of Cell is to support multiple operating systems, such as
conventional operating systems (including Linux), real-time operating
systems for computer entertainment and consumer electronics applications as
well as guest operating systems for specific applications, simultaneously.
Initial production of Cell microprocessors is expected to begin at IBM's
300mm wafer fabrication facility in East Fishkill, N.Y., followed by Sony
Group's Nagasaki Fab, this year. IBM, Sony Group and Toshiba expect to
promote Cell-based products including a broad range of industry-wide
applications, from digital televisions to home servers to supercomputers.
Among the highlights of Cell released today:
* Cell is a breakthrough architectural design -- featuring eight synergistic
processors and top clock speeds of greater than 4 GHz (as measured during
initial hardware testing)
* Cell is a multicore chip capable of massive floating point processing
* Cell is OS neutral and supports multiple operating systems simultaneously
"Today's disclosure of the Cell chip's breakthrough architectural design is
a significant milestone in an ambitious project that began four years ago
with the creation of the IBM, Sony and Toshiba design lab in Austin, Texas,"
said William Zeitler, senior vice president and group executive, IBM Systems
and Technology Group. "Today we see the tangible results of our
collaboration: an open, multi-core, microprocessor that portends a new era
in graphics and multi-media performance."
"Today, we are very proud to share with you the first development of the
Cell project, initiated with aspirations by the joint team of IBM, Sony
Group and Toshiba in March 2001," said Ken Kutaragi, executive deputy
president and COO, Sony Corporation, and president and Group CEO, Sony
Computer Entertainment Inc. "With Cell opening a doorway, a new chapter in
computer science is about to begin."
"We are proud that Cell, a revolutionary microprocessor with a brand new
architecture that leapfrogs the performance of existing processors, has been
created through a perfect synergy of IBM, Sony Group and Toshiba's
capabilities and talented resources, "said Masashi Muromachi, corporate vice
president of Toshiba Corporation and president & CEO of Toshiba's
Semiconductor Company. "We are confident that Cell will provide major
momentum for the progress of digital convergence, as a core device
sustaining a whole spectrum of advanced information-rich broadband
applications, from consumer electronics, home entertainment through various
industrial systems."

I think all these years Rambus has only accomplished one thing-- Rambus
memory interface system adds one simple processor to control traffic between
memory and system bus. As system clock becomes faster, data skew problem
becomes more serious. It is one solution, not the ONLY solution. As RDRAM vs
DDR results shown, the best solution is not to add an active stage. The
addition of the new circuits might become the bottleneck of computer
systems. We saw latency on system with RDRAM. When they show how great the
bandwidth is, they are always feeding the system the ideal data streams.
And Rambus probably get the idea from Adaptec whose SCSI controller is to
use one simple processor to control traffic betweem storage and system bus.
The original idea is from Adaptec. But Rambus wants to extend its patents to
cover everything interfacing computer components.

Name: David Wang (dwang@realworldtech.com) 2/7/05
Today is the day that the CELL processor family gets announced.
I'll be writing a few things about the various papers at ISSCC on CELL, but
before the news conference starts and the papers gets official unveiling,
some interesting data have already been presented in the technical digests.
The CELL processor presented has 1 64b PPC core acting as the traditional
scalar processor, complete with its own L2. The PPE (PowerPC processing
Element) is connected to 8 other SPE's (Synergistic Processing Elements) The
SPE's are the magic glue that is suppose to contain enormous amount of
compute power and a bunch of them gets you the enormously large flop rating
that we've all head much about.
Some stats.
1. 90nm SOI process.
2. Logic depth is functionally equivalent to about 20 FO4 (est), but circuit
speed equivalence is 11 FO4 per stage. The short pipestage circuit depth is
reached with "circuit efficiencies" and Dynamic logic !?!
3. With per stage delay of 11 FO4, the schmoo plots show that the SPE's can
crank from 3.2 GHz @ 0.9V Vdd to 5.2 GHz @ 1.3 V Vdd. The entire chip has
similar frequency/voltage range, but to get to 5.2 Ghz @ 1.3V, each SPE will
eat 11~12W. Add in the rest and the chip will get really hot. 4 GHz @ 1.1V =
4W per SPE seems to be the nominal range.
4. Die size per SPE is 2.5 x 5.81 mm^2. The entire chip with 8 SPE's seems
to be about 17.2 x 12 mm^2. That seems to be an awfully large chip for IBM.
The CPU to be used in PS3/Xbox2 will probably be the 65nm version or it'll
have to have fewer SPE's.
6. As previously announced, the off chip I/O interface is Rambus Redwood and
the memory interface is XDR. Similar clocking/deskewing schemes. Looks to be
about ~50 GB/s BW to memory, and 50~100 GB/s to I/O.
I'll write up articles as the papers are presented.

New Chip to Challenge Intel
02:04 PM Feb. 07, 2005 PT
SAN FRANCISCO -- Setting up a battle for the future of computing, engineers
from IBM, Sony and Toshiba unveiled details Monday of a microprocessor they
claim has the muscle of a supercomputer and can power everything from
video-game consoles to business computers.
Devices built with the processor, code-named Cell, will compete directly
with the PC chips that have powered most of the world's personal computers
for a quarter century.
Wireless Hot Spot burgeoning world of rich media and broadband networks in
mind, can deliver 10 times the performance over today's PC processors.
It also will not carry the same technical baggage that has made most of
today's computers compatible with older PCs. That architectural divergence
will challenge the current dominant paradigm of computing that Microsoft and
Intel have fostered.
The new chip is expected to be used in Sony's next-generation PlayStation
game console. Toshiba plans to incorporate it into high-end televisions. And
IBM has said it will sell a workstation with the chip.
Beyond that, companies are remaining coy about where it might be used and
whether it will be compatible with older technology.
"With this massive computing power, we'll get to the point where we'll get
closer to (a) photo-realistic-type effect that will be able to be generated
by the computer," said Jim Kahle, an IBM fellow.
Supercomputer claims are nothing new in the high-tech industry, and over the
years chip and computer companies have steadily improved microprocessor
performance even without altering chips' underlying architecture.
And while its competitors may well match the Cell chip in performance by the
time it debuts in 2006, it differs considerably from today's processors in
constitution.
Cell is comprised of several computing engines, or cores. A core based on
IBM's Power architecture controls eight "synergistic" processing centers. In
all, they can simultaneously carry out 10 instruction sequences, compared
with two for today's Intel chips.
The new microprocessor also is expected to be able to run multiple operating
systems and programs at the same time while ensuring each has enough
resources. In the home, that could allow for a device that's capable of
handling a video game, television and general-purpose computer at once.
"It's very flexible," Kahle said. "We support many operating systems with
our virtualization technology so we can run multiple operating systems at
the same time, doing different jobs on the system."
Later this year, Intel and Advanced Micro Devices plan to release their own
"multicore" chips, which also increase the number of instructions that can
be executed at once. IBM and Sun Microsystems already sell chips with
multiple cores, mainly for business servers.
Cell also appears to have an advantage in the number of transistors -- 234
million compared with 125 million for today's latest Pentium 4 chips.
Traditional chipmakers, however, have regularly doubled their number of
transistors every 12 to 18 months.
Cell is said to run at clock speeds greater than 4 GHz, which would top the
3.8 GHz of Intel's current top-speed chip.
Cell's designers said they are running a variety of operating systems on the
processor at their lab in Austin, Texas. But they would not say whether
Microsoft's Windows is one of them. In fact, they only confirmed running
Linux.
The PC industry has seen a long line of chips attempt to usurp the x86
architecture pioneered by Intel that dominates today's computers. But all
have failed, and Intel remains the world's largest chipmaker.
In the 1990s, IBM, Motorola and Apple Computer pushed the PowerPC
architecture. Though it's still used by the Apple Macintosh as well as IBM
workstations and servers, it failed to dethrone Intel.
Most recently, Transmeta's Crusoe was supposed to challenge Intel's
dominance in notebooks. Launched at the twilight of the tech boom in 2000,
it gained only marginal acceptance, and the company is now considering plans
to focus on licensing its patents.
Intel has since developed its own mobile chip technology, Centrino.
"Transmeta was also a disruptive influence in the market. And because of
Transmeta, we've got Centrino and the advances that have happened in mobile
computing," said Steve Kleynhans, a Meta Group analyst. "Unfortunately, we
don't really have Transmeta anymore."
For a challenger to succeed in displacing x86, it will have to perform
considerably better since it also will break computing's long-standing
tradition of backward and forward compatibility, said Justin Rattner, who
oversees Intel's Corporate Technology Group.
"They're going to have to show they're able to do things that conventional
architectures at least at the moment are incapable of doing," he said.
"That's the fundamental question."
The Cell's specifications also suggest the PlayStation 3 will offer
realistic graphics and strong performance. But analysts cautioned that not
all the features in a product announcement will find their way into all
systems built on the device.
"Any new technology like this has two components," Kleynhans said. "It has
the vision of what it could be because you need the big vision to sell it.
Then there's the reality of how it's really going to be used, which (is)
generally several levels down the chain from there."

Cell processor with ISSCC in announcement
Finally, the Cell processor of topic dispersed that veil.
It is held in the American San Francisco, "ISSCC (IEEE International
Solid-State Circuits Conference)" with, IBM, the SONY group (SONY, the SONY
computer entertainment), Toshiba developed did the technical announcement of
the "Cell processor" jointly at 3 corporations. Rambus which is cooperative
to 3 corporations and development in the schedule which does the
dissertation announcement regarding Cell with ISSCC, leading that, held the
briefing for press at the Mariotte hotel of the ISSCC meeting place.
As for this time being announced, the technical summary of Cell of the first
generation who is produced with 90nm SOI process. Cell, with multiple core
CPU, loads 9 processor cores in one CPU. For the PC/ server as for CPU, as
for Cell the fact that the quantity of 9 and the CPU core is many is feature
in the same 90nm generation vis-a-vis being the dual core CPU which places 2
CPU cores. In addition, with the multiple core which Intel and AMD develop,
the processor core of the same architecture plural is loaded. Vis-a-vis
that, Cell combines the processor core where 2 types differ.
1 general-purpose processor core and, 8 the relatively simple processor core
is combined in 90nm edition Cell. The general-purpose processor core is
called being something which designates the 64bit POWER architecture of IBM
as the base "POWER Processor Element (PPE)" with. 8 cores, SIMD which faces
to multimedia type processing and the like (Single Instruction and Multiple
Data)"Synergistic Processor Element (SPE)" with are called with architecture
of type. However, it is not the architecture which is specialized in
processing of streaming type, also is widely used very.
- Loading the wide band bus
In addition, other than processor core, new memory "XDR of wide band DRAM
(Yellowstone: Yellow stone)"wide band interface" FlexIO for interface and
tip/chip indirect continuation (Redwood: The redwood)"it loads. The point
where memory and the high-speed bus are taken in has been similar to the K8
system CPU of AMD, but Cell zone is much wider. It is the architecture which
avoids the fact that the bus becomes the problem of processing. Also GPU
which NVIDIA develops, is seen that it is connected to this FlexIO. Each
processor core and the interface group inside Cell "Element Interconnect Bus
(EIB)" with are connected with the internal bus of very is called wide band.
As for the operational frequency of Cell, you say that with the test inside
the laboratory it exceeds 4GHz. Until recently, under the present conditions
which the frequency improvement of Intel CPU which is top speed can blunt,
even in the 90nm generation 4GHz cannot commercialize, as for the frequency
of Cell it is top class. However, as for operational frequency and electric
power consumption because it is trade-off, when being loaded onto the system
really like PlayStation 3, as for the operational frequency of Cell, you say
that it differs depending upon each system.
Efficiency the single precision due to 8 SPE (32bit) reaches to 256 GFLOPS
with floating point arithmetic. This, when with 8 SPE executing the sum of
products calculation of 4 parallel SIMD with 8GHz, is numerical value. You
call 1TeraFLOPS with 1 tip/chip which at the beginning was expected although
it does not reach to the efficiency "of supercomputer class of just a little
front", with general purpose CPU by far it is. In addition, SPE because it
has the mechanism which can execute the streaming processing which is made
poor the general-purpose processor in high speed, becomes much fast than
former general purpose CPU depending upon processing. You say that
efficiency of 10 times can be actualized depending upon application.
Die/di size (area of semiconductor itself), with present trial manufacture
tip/chip 221mm2. This to be a little smaller than 239.7mm2 of the first
generation Emotion for PlayStation 2 Engine, 0.18 ? m edition Pentium 4
(Willamette: ??????) almost it is the same as 217mm2. In other words,
productivity and production cost mean the same level basically.
- PowerPC and instruction set interchangeable PPE
PPE of Cell is the processor core of POWER architecture, but you say that it
is not diversion of the existing core, it is the new core which from one was
developed with scratch. However, as for instruction set existing POWER
system CPU and being completely interchangeable, as for the software it is
possible to be able to send basically that way. In addition, with PPE,
PowerPC 970 (G5) with in the same way, AltiVec and interchangeable vectoring
operational function "VMX" of Motorola are mounted. In other words, PPE
PowerPC 970 (G5) with means the interchangeability.
Furthermore, PPE Hyper-Threading and similar SMT of Intel (Simultaneous
Multithreading) loads also function, it is possible to execute two threads
simultaneously. With PPE and 8 SPE which mount SMT of 2way, altogether Cell
10 threads can be executed in parallel. In other words, when you see from
software side, in order for there to be 10 CPU in Cell, it means to be
visible. PPE has L2 cash of 512KB.
As for SPE which 8 is loaded in Cell, it is the SIMD type processor which
can do the same processing simultaneously in 1 order vis-a-vis the plural
data. It is possible to think that it became the processor where SSE unit of
X86 type CPU becomes independent. Same as SSE, the single precision floating
point data of 32bit 4 and integer data 4 can be processed simultaneously in
1 order.
In addition, with SPE, the various architecture which are optimized in
streaming processing are taken in. For example, we have 128 these 128bit
registers, developing the loop which is in the midst of programming, to SIMD
converting, we are possible also to process in parallel. In addition, "Local
Store (LS)" of 256KB with the memory which is called is loaded.
The major feature of Cell is the point where bus the inside and outside the
tip/chip is very wide band. EIB which connects each element inside Cell the
transfer of 768bit is possible in 1 cycle. Because the usual on-chip bus is
128bit and 256bit, Cell is especially high speed. In addition, memory loads
the interface of the next generation memory XDR of Rambus DRAM at dual,
memory zone reaches to 25.6GB/sec. With the zone of 76.8GB/sec, dividing
into 2 ports, can FlexIO of interface between the tip/chip use. In other
words, it can connect 2 companion tips/chips such as GPU and the I/O chip.
In addition, like K8 of AMD also can plural Cell connect mutually with
FlexIO.

channels. That ain't gonna come cheap. Nor will the 6 or 8 (at
least) memory chips required. High bandwidth I/O is going to be
expensive as well, and all this is probably going to require at least
an 8 layer PCB, adding more cost.
I'm really having a tough time figuring out just how Sony plans to get
this console into the ~$300 price range that they will probably need

tough.

I like how they make it sound small as compared to PC chips. The
actual processor is ~220mm^2 on a 90nm process.
For comparison, Intel's latest "Prescott" P4 has a die size of 112mm^2
and AMD's Athlon64 weighs in at a mere 84mm^2, both on a 90nm process.
Even the dual-core versions of these two processors will be smaller
than a Cell.
Sony plans to use the new Cell in its PlayStation 3, likely to be introducedin 2006, and Toshiba plans to use the chip in advanced high-definitiontelevisions, also to be introduced next year.
Has anyone figured out how this processor is actually going to improve
a television in any way? I'm really curious about this one. Just
what is it that they're planning on processing in the TV signal? DRM?
However, many industry executives and analysts say that Cell's impact mayultimately be much broader, staving off the PC industry's efforts todominate the digital living room and at the same time creating a new digitalcomputing ecosystem that includes Hollywood, the living room andhigh-performance scientific and engineering markets.
Awful big claims for a processor that has exactly ZERO software
support. I've said it MANY times before and I'll say it many times in
the future, hardware is cheap, software is *EXPENSIVE*
"Cell has been optimized for broadband-rich applications," said Jim Kahle,I.B.M.'s director of technology at the Design Center for Cell Technology,the headquarters in Austin, Tex., for the I.B.M., Sony and Toshibapartnership.
What, exactly, is a "broadband-rich" application? Playing computer
games?
He said that I.B.M. had refined a technology also being developed by Intelcalled "virtualization," which is designed to isolate applications from oneanother. Originally used in mainframe computing applications, the technologyis now being exploited by consumer electronics designers to run demandingapplications like video decompression and decryption simultaneously.
Hmm.. DVD players can do both decompression and decryption on about $1
worth of embedded controller + ASIC. How much more compression and/or
encryption are they really planning on here?

Cell consortium reveals chip details, claim 4GHz + clock speeds
Rob Fahey 12:11 08/02/2005
Few surprises at unveiling, but eight-SPU design and high clock speeds are
confirmed
Official details of the Cell microprocessor have been revealed by partners
IBM, Sony and Toshiba, with the multi-core architecture set to be capable of
processing ten threads on a single chip clocked at over 4Ghz.
The chip package will consist of a 64 bit Power processor - similar to the
CPUs being used in the Xbox 2 and PowerMac G5 systems - which can process
two threads simultaneously, along with eight "synergistic processing units".
These SPUs are the real horsepower behind the chip; each one has 256KB of
its own memory and can handle computing tasks separately from the main
processor, which will be responsible for dividing up tasks between the SPUs
and running the operating system.
While clock speeds are an almost entirely meaningless measurement of
processor performance, especially when comparing chips as radically
different as Cell and the existing Intel / AMD families, much attention has
been focused on the claim that the Cell could start out at speeds of over
4GHz.
Despite not being a clear indicator of actual performance, the speed is
still a PR coup for IBM and its partners - since Intel's range of chips
currently maxes out at 3.8GHz, while Cell may go as high as 4.6GHz in its
early incarnations.
More useful as a performance measurement is the chip's rating in terms of
calculations per second, or "gigaflops", with Cell rated at 256 gigaflops
according to IBM - a fair bit short of an entry in the Top 500
Supercomputers list, which starts at 851 gigaflops, but still enormously
powerful for a single chip, and of course the chips are designed to operate
efficiently in clusters.
Indeed, it's widely expected that the PlayStation 3 could boast as many as
four Cell chips, which would give a theoretical CPU performance of over 1000
gigaflops, or one teraflop - a very theoretical measure, admittedly, but
still enough to earn the PS3 a place on the supercomputer list.
Another aspect of the performance which IBM has been quick to champion is
the memory bandwidth available to the Cell, with the design utilising RAMBUS
interface technology that delivers an unprecedented one hundred gigabytes
per second of bandwidth to the chip, with separate interfaces for
communicating with system memory and with other CPUs.
Despite Sony's claims, one thing we won't be seeing in the near future is
Cell being used in portable devices such as mobile phones - according to an
IBM spokesperson, the chip, which is initially being manufactured on a 90
nanometre process but will eventually move down to 65 nanometre, runs hot
enough to require a cooling fan, like most desktop CPUs.
Spokespeople from the Cell consortium were quick to point out the
flexibility of the system, saying that the multi-processor architecture
could be used in a variety of different ways by game developers or other
software creators.
However, game developers contacted by GamesIndustry.biz downplayed
speculation that the PS3 would be incredibly difficult to program as a
result of the new architecture, saying that the main difficulty would be the
move to a multi-core system - a design shared by the Xbox 2 and almost
certainly by the Nintendo Revolution.
The game development model which is used for PlayStation 2, where a few
programmers work directly with the low level code to create libraries for
specific functions and other developers simply use those libraries, masking
the complexity of the underlying system, is likely to work just as well on
PlayStation 3, while the prevalence of middleware such as Criterion's
RenderWare or the Havok physics engine will also make the transition less
painful.
Another factor fingered by developers is the fact that Sony's PlayStation
Portable libraries and documentation have been widely praised by those
working on the system, indicating that Sony has learned an important lesson
from the PS2 launch - where much of the development difficulty lay not with
the system itself, but with poorly translated (or un-translated)
documentation and difficult to use libraries.
Along with the Cell processors, the PlayStation 3 is also set to use a
graphics chipset from NVIDIA, which will be based on the company's next
generation of GPU, following on from the hugely successful 6000 series of PC
graphics cards.

I have to agree with you on that, seems that Sony is playing a Microsoft

I am surprised that no one has posted this link to a brief overview of the

I wonder how Intel will respond to this new development, seems like a

That assumes it runs at 100% all the time. Are there any games today
that max out a PS2, Xbox, or a high end PC GPU for more than a few seconds
at a time? I'm sure there are complex sequences where you hit the max
but it isn't as though you have that kind of complexity all the time.

I don't see that cost as a problem for putting them in PS3 or HDTVs. And
you can cut that size pretty much in half for 65nm which will be where the
bulk of Cells are made, and it'll really be cheap later in life as a 45nm
product.

You are assuming that they don't use multi channel memory chips. No reason
they can't make a single 1Gb XDR chip that has 3 or 4 XDR interfaces with
independant memory arrays, and use two if they wanted 256MB which would
probably be a reasonable target.
For everything else, when they will be selling PS3s in the tens of millions,
perhaps as many as a hundred million over its lifetime, economies of scale
can make a lot of things cheap that wouldn't be on say a PC motherboard,
most of which are probably lucky to sell 100K units considering their short
lifetime and field filled with many nearly identical competitors.

Introducing the IBM/Sony/Toshiba Cell Processor -- Part II: The Cell
Architecture
By Jon "Hannibal" Stokes
In today's session, IBM introduced the overall architecture of the Cell
processor. Unfortunately, they didn't include many more microarchitectural
details in today's session than they did in yesterday's. Most of the session
covered issues like power management, clocking, the design process, and so
on. So today's article is going to be more along the lines of a follow-up to
yesterday's piece. I'll fill in the new information that I've picked up, as
well as clarifying leftover questions from yesterday.
The Cell's basic architecture
The basic architecture of the Cell is described by IBM as a "system on a
chip" (SoC) design. This is a perfectly good characterization, but I'd take
it even further and call Cell a "network on a chip." As I described
yesterday, the Cell's eight SPUs are essentially full-blown vector
"computers," insofar as they are fairly simple CPUs with their own local
storage.
These small vector computers are connected to each other and to the 512KB L2
cache via a element interface bus (EIB) that consists of four sixteen-byte
data rings with 64-bit tags. This bus can transfer 96 bytes/cycle, and can
handle over 100 outstanding requests.
The individual SPEs can use this bus to communicate with each other, and
this includes the transfer of data in between SPEs acting as peers on the
network. The SPEs also communicate with the L2 cache, with main memory (via
the MIC), and with the rest of the system (via the BIC). The onboard memory
interface controller (MIC) supports the new Rambus XDR memory standard, and
the BIC (which I think stands for "bus interface controller" but I'm not
100% sure) has a coherent interface for SMP and a non-coherent interface for
I/O.
Unfortunately, today's session was severly lacking in information on the
64-bit PPC core that handles the Cell's general-purpose computing chores. We
do know that this core has a VMX/Altivec unit, at least one FPU, and
supports simultaneous multithreading (SMT). It's also in-order issue, like
the SPUs. So it appears that this core also lacks an instruction window,
presumably for the same reasons that the SPUs do (i.e. to save on die space
and cut down on control logic.) I have in my notes that the core is
two-issue, like the SPUs, but I can't find this corroborated anywhere else.
So it's possible that the core only issues two instructions per cycle peak,
i.e. one from each currently-running thread. I'd imagine that if this is the
case, this core's pipeline is very short. This would fit with the SPUs, in
which the pipeline was also kept short and simple.
The entire Cell is produced on a 90nm SOI process with 8 layers of copper
interconnect. The Cell sports 234 million transistors, and its die size is
221mm2. (This is roughly the size of the Emotion Engine at its
introduction.) The PPC core's 32KB L1 cache is connected to the system L2
cache via a bus that can transfer 32 bytes/cycle between the two caches.
The Cell and Apple
Finally, before signing off, I should clarify my earlier remarks to the
effect that I don't think that Apple will use this CPU. I originally based
this assessment on the fact that I knew that the SPUs would not use
VMX/Altivec. However, the PPC core does have a VMX unit. Nonetheless, I
expect this VMX to be very simple, and roughly comparable to the Altivec
unit o the first G4. Everything on this processor is stripped down to the
bare minimum, so don't expect a ton of VMX performance out of it, and
definitely not anything comparable to the G5. Furthermore, any Altivec code
written for the new G4 or G5 would have to be completely reoptimized due to
inorder nature of the PPC core's issue.
So the short answer is, Apple's use of this chip is within the realm of
concievability, but it's extremely unlikely in the short- and medium-term.
Apple is just too heavily invested in Altivec, and this processor is going
to be a relative weakling in that department. Sure, it'll pack a major SIMD
punch, but that will not be a double-precision Alitvec-type punch.

It doesn't much matter, you need to design for maximum power draw
unless you want your system to shut down randomly. Well, actually I
suppose you could take the Intel route and use thermal throttling to
prevent maximum power draw from overloading a borderline cooling
solution, but I haven't heard of such a solution for the Cell.
Plus, this is at 90nm, and unless they are planning to ship the PS3 intime for this xmas, it'll be built on 65nm and the power needs would bereduced.
I'm not sure that they will be reduced all that much. Leakage current
is going WAY up for the 65nm node. With over 200M transistors it's
going to be TOUGH to keep leakage in check.
Supposed to be about 220mm^2 total. Rather hefty processor. At a(very) rough guess that should have a per-processor cost of somewherearound $70-$80.I don't see that cost as a problem for putting them in PS3 or HDTVs. Andyou can cut that size pretty much in half for 65nm which will be where thebulk of Cells are made, and it'll really be cheap later in life as a 45nmproduct.
At 65nm it should be cheaper to make, though I don't expect much
volume of 65nm chips until late 2006/early 2007. I know IBM and Intel
are both aiming for almost a year earlier, and maybe I'm just being a
cynic, but I don't think they're going to get volume out anywhere
close to on time.

channel can/do work), though it would still seem like those would be
fairly expensive chips.
For everything else, when they will be selling PS3s in the tens of millions,perhaps as many as a hundred million over its lifetime, economies of scalecan make a lot of things cheap that wouldn't be on say a PC motherboard,most of which are probably lucky to sell 100K units considering their shortlifetime and field filled with many nearly identical competitors.
I'm sure that Sony will make a push for it, I'm just not convinced
yet. I would expect that the console will first come being rather
expensive ($500+?) and might have some trouble selling. Economies of
scale only take you so far, eventually you've got to pay for
everything.
Note that there are also some rumors floating around that the PS3
might use multiple Cell processors, not just one. Now, I'm not taking
these rumors as fact by any means, but if they do turn out to be
accurate then it would push the cost up quite a bit higher.

Despite my rather distaste for Rambus the company and recognizing that

the PS3 their stuff makes VERY good sense.
With the way that the PS2 processor and this new Cell processor work,
combined with the nature of the machine (ie to play games), bandwidth
is likely to be quite important while latency will be somewhat less
so. Remember that these processors are going to be doing a lot of
work traditionally associated with GPUs in a PC. Rambus' solutions,
both XDR now and RDRAM back when the PS2 was new, do offer VERY high
per-pin bandwidth and that's just the sort of thing that these
consoles need. The processors also have integrated memory controllers
which helps avoid some of the potential issues with Rambus in PCs. To
top it off, the memory chips are getting soldered right onto the
system board rather than hanging off multidrop sockets on the system
board.
Basically a PC and the PS2/PS3 have rather different designs and
different requirements. Hmm.. different solutions for different
problems... whodda thunk it! :>

Top 7 Myths of the New Cell Processor:
by Modab (153378) on Wednesday February 09, @04:56AM (#11616545) There are
so many people saying dumb things about the Cell and the upcoming PS3, I
have to set some things straight. Here goes:
1.. The Cell is just a PowerPC with some extra vector processing.
Not quite. The Cell is 9 complete yet simple CPU's in one. Each handles
its own tasks with its own memory. Imagine 9 computers each with a really
fast network connection to the other 8. You could problably treat them as
extra vector processors, but you'd then miss out on a lot of potential
applications. For instance, the small processors can talk to each other
rather than work with the PowerPC at all.
2.. Sony will have to sell the PS3 at an incredible loss to make it
competitive.
Hardly. Sony is following the same game plan as they did with their
Emotion Engine in the PS2. Everyone thought that they were losing 1-200
bucks per machine at launch, but financial records have shown that besides
the initial R&D (the cost of which is hard to figure out), they were only
selling the PS2 at a small loss initially, and were breaking even by the end
of the first year. By fabbing their own units, they took a huge risk, but
they reaped huge benefits. Their risk and reward is roughly the same now as
it was then.
3.. Apple is going to use this processor in their new machine.
Doubtful. The problem is that though the main CPU is PowerPC-based like
current Apple chips, it is stripped down, and the Altivec support will be
much lower than in current G5s. Unoptomized, Apple code would run like a G4
on this hardware. They would have to commit to a lot of R&D for their OS to
use the additional 8 processors on the chip, and redesign all their tweaked
Altivec code. It would not be a simple port. A couple of years to complete,
at least.
4.. The parallel nature will make it impossible to program.
This is half-true. While it will be hard, most game logic will be
performed on the traditional PowerPC part of the Cell, and thus normal to
program. The difficult part will be concentrated in specific algorithms,
like a physics engine, or certain AI. The modular nature of this code will
mean that you could buy a physics engine already designed to fit into the
128k limitation of the subprocessor, and add the hooks into your code. Easy
as pie.
5.. The Cell will do the graphics processing, leaving only rasterezation
to the video card. Most likely false. The high-end video cards coming out
now can process the rendering chain as fast as the Cell can, looking at the
raw specs of 256Gflops from the Cell, as opposed to about 200GFlops from
video cards. In two years, video cards will be capable of much more, and
they are already optomized for this, where the Cell is not, so video cards
will perform closer to the theoretical limits.
6.. The OS will handle the 8 additional vector processors so the
programmer doesn't need to.
Bwahahaha! No way. This is a delicate bit of coding that is going to
need to be tweaked by highly-paid coders for every single game. Letting on
OS predictively determine what code needs to get sent to what processor to
run is insane in this case. The cost of switching out instructions is going
to be very high, so any switch will need to be carefully considered by the
designer, or the frame-rate will hit rock-bottom.
7.. The Cell chip is too large to fab efficiently.
This is one myth that could be correct. The Cell is huge (relatively),
and given IBM's problems in the recent past with making large, fast PowerPC
chips, it's a huge gamble on the part of all parties involved that they can
fab enough of these things.

Tiny new chip packs a lot of power
IBM East Fishkill plant to make microprocessor
By Craig Wolf
Poughkeepsie Journal
What appears to be the hottest microprocessor chip in the world looked even
hotter Monday as IBM Corp., Sony Group and Toshiba Corp. revealed its
performance is 10 times that of current chips.
The tech trio's ''Cell'' chip will be made at IBM's 300-millimeter plant in
East Fishkill this summer to satisfy needs of Sony and Toshiba for a new
generation of broadband, video-hungry home entertainment systems. The plant
already makes a version of the chip being used in computer workstations
suited to game development. The plant is being expanded by IBM and six
partners, including Sony and Toshiba.
New Cell details came out in San Francisco at the International Solid State
Circuits Conference, a major annual technical gathering. Monday's
revelations were whoppers.
8 processors per chip
The chip has eight cores, or separate processors, that operate
synergistically. Industry chatter was predicting four cores. It has run at
speeds of better than 4 gigahertz, or billions of cycles per second,
somewhat ahead of Intel Corp.'s best speeds. It can run several kinds of
software simultaneously, including Linux and proprietary gaming programs.
More details are to come out today, but analysts were impressed already.
''This is still the biggest chip technology advance in probably 20 years,''
said Richard Doherty, research director at Envisioneering Group in Seaford,
Nassau County.
If anything, claims of a 10-fold leap in performance are understated,
Doherty said. ''Our estimate is 10 to 20, so they're being conservative,''
he said.
He added Cell developers said they could have put 16 cores on the same size
chip if they had thought it necessary.
Touted as a ''supercomputer on a chip" by the trio, Cell may well find use
in business environments including supercomputing, but its first and main
function will be to lift the computerized entertainment world to new levels.
Cell is aimed at your house. The chip is expected to be used in Sony's
next-generation Playstation as well as in high-definition television sets.
''It's very flexible,'' said Jim Kahle, an IBM fellow, quoted by the
Associated Press. ''We support many operating systems with our
virtualization technology so we can run multiple operating systems at the
same time, doing different jobs on the system.''
What that could mean, for example, is that gamers in different locations
could play online using Linux, an open-source software widely available
around the world. The chip could handle that work as well as running Sony's
software that controls the game logic and characters.
''Having hierarchical operating systems, if you will, that's a whole big
step in computing,'' Doherty said. ''In entertainment, that's tremendous.''
Cell was developed by the trio at IBM's Austin, Texas, facility beginning in
2001. It contains 234 million transistors in a space of 221 square
millimeters, about the size of a fingernail. It's made with 90-nanometer
process, so called because it creates features that small, a nanometer being
a billionth of a meter.
Executives toasted their teamwork in a statement issued Monday. Masashi
Muromachi, a corporate vice president of Toshiba, said, ''We are proud that
Cell, a revolutionary microprocessor with a brand new architecture that
leapfrogs the performance of existing processors, has been created through a
perfect synergy of IBM, Sony Group and Toshiba's capabilities and talented
resources.''
Whether the team's work eclipses that of leader Intel remains to be seen.
Monday was also the day on which Intel said it was now making a
two-processor chip.
''It's poor timing,'' Doherty said. ''The twin-piston engine comes out the
same day as a V-8.''

It really doesn't matter. Whatever price point you look at ($60, $90,
$200, $400) the rate of performance improvement over time is about the same
(or slightly higher at the low end). Today you can get for $60 what cost
$400 two years ago. You can get for $90 what cost $300 last year.
A dedicated graphics chipset that is designed as part of an integrated
system that will be build as a large quantity of identical units changes the
economics significantly. A large part of the cost of selling a graphics card
is the physical interface, packaging, testing, shipping, advertising,
stocking, tooling runs, and customer support. When the graphics chipset is
part of a larger unit, all of these costs are dramatically lower. So an
integrated game system can contain the equivalent of a $200 graphics card
for an added cost of only about $50.
Due to economics of scale and buying in bulk, the price different
between the equivalent of a $200 graphics card and the equivalent of a $300
graphics card is probably negligible. Remember, the graphics chip vendors
want to push up their ability to produce high-end chips in quantity anyway.
This gives them a competitive edge in the PC graphics market.

It doesn't much matter, you need to design for maximum power draw unless you want your system to shut down randomly. Well, actually I suppose you could take the Intel route and use thermal throttling to prevent maximum power draw from overloading a borderline cooling solution, but I haven't heard of such a solution for the Cell.
Cell is performing thermal throttling as well. It's commonplace now (and in
all honesty it's just a first order technique).
Plus, this is at 90nm, and unless they are planning to ship the PS3 intime for this xmas, it'll be built on 65nm and the power needs would bereduced. I'm not sure that they will be reduced all that much. Leakage current is going WAY up for the 65nm node. With over 200M transistors it's going to be TOUGH to keep leakage in check.
True...
So it boils down to where your power is spent. Leakage current from 65nm
vs. the PPE and SPE functional units? Ahhh, I'd have to guess the
functional units but I don't have a firm enough grasp on power
considerations to be sure.

I guess my expectations for Cell were pretty high. But i guess most of
the size of the die is for accomodating the greater number of pins
required to feed the behemoth. 8 Vector processor on a die is close to
being the Cray's X1 node and they had to cool it using freon. I guess
the cache is way too small (2.5MB is nothing for a high performance
Vector processor)

I'm not sure that's true. My son manages a "software" retail store. It's

I think the concept is to make everything part of a distributed

might not need that much processing power to handle HDTV decryption
but you can link it up to your Cell PC to offload some of that wedding
video encoding you're doing... along with your radio, refrigerator and

Just think of how much $$$ we're talking about here if everything runs

Intel has no answer to the 'Cell' processor; will Apple use it in
Macs?
Wednesday, February 09, 2005 - 11:50 PM EST
"IBM, Sony and Toshiba unveiled a new supercomputer-on-a-chip Monday
that could disrupt Intel's dominance of the computer industry and change the
nature of digital entertainment," Dean Takahashi reports for The San Jose
Mercury News. "The Cell chip will first be used in Sony's PlayStation 3
video console next year, with Toshiba planning to use the Cell in digital
television sets and IBM intending to put it in computer servers and work
stations in the near future."
"The partners say the first Cell chips, which can simultaneously
juggle multiple computing tasks, will have 10 times the processing power of
comparable Intel chips. Eventually, the technology could pack the power of a
supercomputer in a handheld device," Takahashi reports. "That would mean
consumers would be able to buy a machine that runs video games so
realistically that players will feel like they are inside the animated world
of, say, 'Shrek 2.'"
"'This is a shot across the bow for Intel,' said Richard Doherty, an
analyst at the Envisioneering Group, a consulting firm in Seaford, N.Y.
'Intel still uses an architecture that came from a calculator chip,' he
said. 'Cell comes from a clean sheet of paper, where the engineers had the
freedom to design from scratch for machines that manipulate images.' There
is no indication that Intel has a response to the Cell chip in the works. On
Monday, the Santa Clara chip maker, whose chips run 85 percent of the
world's PCs, said it will begin selling PC microprocessors with two
processors on a single chip by summer," Takahashi reports.
"No one expects the new Intel chips to have anywhere near the
processing power of the Cell, which will be made by IBM and Sony... Analysts
were intrigued that the Cell uses IBM technology that enables it to run any
operating system," Takahashi reports. "Kevin Krewell, editor of the
Microprocessor Report, said that raises the possibility that Apple Computer,

Not too likely. The cell is not a general purpose CPU; Most programs
have a working set larger than the 256k memory the Cell supports, and
changing them to work in 256k increments would rather hard.
The Cell seems to be intended for use as a sort of co-processor, and
maybe they could be used to build a sort of GPU. But the benefits will
be in any event pretty limited.

No, at least the way I "read" things the cell's cpu is pretty much
a stripped-down in-order PowerPC. The 'G5' is very much out-of-order and
hardly stripped.

And a fat load of good it's done the Alpha. To be fair though, I
don't think that it's collapse had anything to do with using Rambus
memory one way or the other.
Besides, ever there it's not exactly showing tremendous performance.
Even in SPEC CFP2000, kind of the ideal benchmark for this
super-bandwidth setup, the EV7 is still being beaten by current x86
processors. When looking at other tests it's even less impressive.
Now again those results are not necessarily an indication that Rambus
is a failure because there are MANY other issues holding the EV7s
performance back (only some of which are technical). Unfortunately
it's impossible to say just how well/poorly a theoretical EV7 with a
DDR-SDRAM interface might have compared to the RDRAM one. However I'm
not sure that one can really hold up EV7 as a success story for Rambus
in any way.
I guess my expectations for Cell were pretty high. But i guess most ofthe size of the die is for accomodating the greater number of pinsrequired to feed the behemoth. 8 Vector processor on a die is close tobeing the Cray's X1 node and they had to cool it using freon. I guessthe cache is way too small (2.5MB is nothing for a high performanceVector processor)
Keep in mind that this chip and the Cray X1 are designed for VERY
different workloads. The Cell is likely to be rather weak
(comparatively speaking) when running scientific computing as compared
to how it works in a gaming console.

The Cell's PowerPC core is more definitely NOT a G5 processor, nor is

Sure, they could, but they wouldn't be anywhere near as fast as any
current processors unless you can make use of the vector engine. And
doing that means changing ALL of the software, and that is
*EXPENSIVE*.
We will definitely NOT see the Cell processor (or it's descendants)
showing up in any meaningful way (ie not just a couple special-purpose
workstations from IBM) as the main processor in desktop computers for
AT LEAST 5 years, probably more like 10+ years if ever. And yes, you

I've wondered the very same thing myself. To me, from the outside at
least, it seems like it would make sense. Rambus memory has been used
in video cards before, but only in some very rare situations. I don't
even think there would be much of a cost difference for the memory
chips even, given that video cards use very high-end/high speed GDDR3
memory, quite a bit more expensive than the DDR memory used in desktop
PCs.
However nVidia has commented before that they have evaluated Rambus
memory on more than one occasion and found it to be unsuitable for
their application. It's always made me wonder if maybe they know
something that the rest of us don't? Or maybe their decision was only
partly based on technical reasons and partly on more political/legal
related ones? Or maybe it has to do with Rambus licensing fees for
the memory controller rather than for the memory itself?
In short, I really don't know what the answer is here.
In essensce, what's so different between the PS3 and graphics cardsthat one goes with Rambus whereas the others go with DDR(2)?
Not much from where I'm standing.

Back to Basics
The fundamental task of a processor is to manage the flow of data through
its computational units. However in the past two decades, each successive
generation of processors for personal computers has added more transistors
dedicated to increasing the performance of spaghetti-like integer code. For
example, it is well known that typical integer codes are branchy and that
branch mispredict penalties are expensive; in an effort to minimize the
impact of branch instructions, transistors were used to develop highly
accurate branch predictors. Aside from branch predictors, sophisticated
cache hierarchies with large tag arrays and predictive cache prefetch units
attempt to hide the complexity of data movement from the software, and
further increase the performance of single threaded applications. The
pursuit of single threaded performance can be observed in recent years in
the proposal of extraordinarily deeply pipelined processors design
