Parte 2:
At present, the processor's design is still being held tightly under wraps, but sources indicate that in addition to its ability to deliver one trillion calculations per second or more of floating-point calculations, Cell will likely employ somewhere between four and 16 processor cores, or cells, per chip (hence the technology's label). Accordingly, while a game console might utilize a chip with 16 cores (some cores performing computational functions, others controlling audio and graphics), a less complicated "appliance" like a set-top box would require fewer. At least, that's a précis offered by Peter Glaskowsky, editor in chief of the influential industry newsletter "Microprocessor Report."
Cell computing will also facilitate a distributed style of networking that performs computing tasks in much the same way a cell phone network routes calls. Thus, for example, the PlayStation 3 will be able to use its broadband Internet connection to draw additional computing power from idle processors across the Internet. If still more horsepower is required, the PlayStation 3 can even tap into a home network to enlist support from other available machines. Put simply, Cell allows pieces of a computing task to be distributed among all available processors to harness their combined power.
This all dovetails with comments made by Shin'ichi Okamoto, chief technical officer for Sony Computer Entertainment, during a speech made at the 2002 Game Developers Conference. He spoke then of a technology he referred to as parallel computing, where multiple processors dramatically increase performance by splitting tasks. Okamoto also showed a diagram of an early project referred to by Sony as "GScube" comprised on 16 PS2s paired with a video merger and integrated into a single box. And, he went on to hint at a project that Sony was working on with IBM and Toshiba regarding a "cell processor," a technology that Okamoto confirmed would be at the core of the third-generation PlayStation.
RDRAM This supercomputer-on-a-chip, however, is in need of external technology that will enable the high-speed interfacing between chips that it requires to perform its magic. That's where Rambus comes in. Best known for the RDRAM employed in PCs and game consoles (Nintendo and Sony), Rambus specializes in chip interfaces, electronic ports that facilitate the communication between chips. This past year, it licensed its memory technology to Sony and Toshiba, companies which plan to use it in "unspecified" new products due to reach market in approximately three years. Understandably, shares of both companies jumped based on speculation that Rambus' technology will be employed in combination with Cell in Sony's PlayStation 3.
Sendo q esse RDRAM eh um chip....!!
Era pra te a voto dele...soh q ñ sei como coloca....!!
