what a F***** trash can???
i poted 1000 articles on CELL and ps3 and an illeterate comes up with bizarre info.
You posted a lot of articles that you didn't understand, let me try to explain it in easier terms. The Cell architecture by itself doesn't produce a magically high performance processor, unless you use the SPUs. It can happily run as a plain vanilla PowerPC chip. The SPUs are where it gets interesting because they execute separately from the main processor core, and are quite fast - if a bit limited. You have to send the SPU a small program to perform a small task along with some input. The main program runs on the primary core and sends these jobs off to each of the SPUs to offload the computation. The main program accepts the SPU's results, which might be a physics calculation or the like. It then incorporates these results into its own calculations.
The aggregate performance of the SPUs, combined with the performance of the primary core, is where the performance figures come from. 100% utilization is not a simple task, especially in a video game where many different things are happening at once and can change quickly. It needs to be handled either by the programmer or the compiler, and the last I'd heard IBM wasn't finished with their compiler.
parallelliaaaaaaaaaaaa .................what the F***** is this guy saying..................................have been reading any of those links i posted from IBM, MC, UC, MIT
The word you're looking for is parallelization. In this context, it means doing more than one thing at a time.
