Hannibal over at Ars Technica describes the Cell Processor’s Architecture. Very good highlevel description. This is unlikely to be used in general purpose PCs anytime soon – look Hannibal’s closing paragraph’s describing why he doesn’t think Apple will use it anythime soon. Basically, to fit these simple CPU’s (not much more than an ADDer and local cache), the main CPU on the chip is also severly handicapped. But it is possible that 10 years down the road, when we can fit enough transitors on a single chip, we could see chip designs with several full-power CPUs joined togather on a bus something like this within the chip. Hello consumer parallel processors :).
