De uma forma legal.

darão o nome de 1cell a exemplo um pu+2alus(i/o+cmi) ou mesmo 1pu+4alus(i/o+cmi) ou será 1 cell cada alu
Microprocessor Report's Tom Halfhill published an investigation into a detailed patent filed in 2001, and published by the USPTO in October, and he was kind enough to discuss it with us. We'll refer to it as the '734 patent.
Inside Cell
..........................
The '734 patent calls the basic hardware unit a PE, or 'processor element'. Rather confusingly, a PE consists of a 'processor unit' or PU, and an array of attached, er, processing units or APUs. The patent, Tom notes, says that the "preferred" PE configuration is eight APUs. The "preferred embodiment" of an APU is 128kb of SRAM, 128 x 128-bit registers, four integer units and four floating point units. Some of these may be specialized for tasks such as shading.
..........................
A hypothetical Cell processor with eight of these APUs could achieve 32 BOPS and 32 gigaFLOPS at only 250MHz," writes Tom. Or a teraflop at 1Ghz. This is an order of magnitude higher than today's workstations in what could be a low cost, low power machine.

Deve estar errado.

Finally, I should mention that I'm really looking forward to seeing what IBM has up their sleeve with this. I'm going to refrain from doing any speculating this close to the launch, but I will go ahead and hint at some of what I actually know. I once speculated somewhere (I can't find the link right now) that IBM would probably start introducing a basic core design at the top end and then migrating that design down into other niches, just like they've done with the POWER4->970 shift. I stand by this bit of speculation.
Also, regarding rumors of potential Apple uses of the Cell processor, I don't think it's at all likely (at least not anytime soon) for reasons that will become clear in Monday's session.

Super Cell
.........................
We've managed to glean some inside tidbits. A single Cell chip is expected to be capable of surpassing 250 billion floating point operations, or 250 gigaflops, per second, rivaling the best mid-1990s supercomputer. In flops, it is six times as fast as Nvidia's new graphics chip.
.........................
Each Cell chip will have between eight and ten separate processing cores on one piece of silicon (a final decision is pending), compared to two for the latest Pentium chips.
.........................
Intel is watching Cell warily, but Intel spokesman Howard High says that while the chip may be successful in videogame consoles, he doubts it would reverberate beyond into the realm of PC computers. "The Japanese tend to shoot high in terms of their goals. So far they haven't had a successful general-purpose microprocessor," says High.
.........................
Sony and IBM have announced plans for a workstation combining multiple Cells that, acting in concert, will reach 16 trillion flops, ranking alongside the world's top ten supercomputers. It will be aimed at engineers and Hollywood animators. This figure is "probably a p.r. exaggeration," the Cell engineer says, but future workstations containing racks of 32 chips will be able to attain this speed. Toshiba has plans for a Cell-based hi-def TVset in 2006.
.........................
One surprise, says the engineer, would be if Cell lives up to the rumor going around the development team that the consortium is on its way to production using advanced 65-nanometer technology
Since the two giants established their hegemony around 15 years ago, we've seen many candidates threaten to unseat the PC duopoly. RISC, Unix, and Internet appliances (with or without Java) were all taken seriously as competitive threats in Santa Clara and Redmond. The Cell, from Sony, IBM and Toshiba is the latest; it will be unveiled next week in San Francisco and will ship later this year in the PlayStation3 console and in enterprise infrastructure from IBM. But what will a world with Cell supreme look like?
.........................
Now, we have to ask - what chances does it have of succeeding?
There are technical reasons that weigh heavily on whether each of these propositions will succeed. For example, Intel's Itanium depends on compilers parallelizing the code, and has foundered because this is difficult, and cheaper, dumber does a better job. Cell hardware will need really great compilers to work. But in the end, technical arguments like these won't be the decisive factors. We have to step right back and look at how and why people depend on computer technology, and exactly who in the world stands to benefit from each - and there are many - of the possible "victory" scenarios.
So until the chapter arrives on Monday covering key aspects of the CELL patent itself, I’d like to know if you still think that President Ando’s visit to MacWorld was really incidental.
"Cell will make possible a transformation in entertainment like that from novels to movies,"says Ken Kutaragi, president of Sony Computer Entertainment.
