IBM's CELL Processor: Preview to Greatness?
IBM, in cooperation with fellow industry giants Sony and Toshiba, recently announced a new processor, called the Cell. The Cell processor contains a powerful 64-bit Dual-threaded IBM PowerPC core but also eight proprietary 'Synergistic Processing Elements' (SPEs), essentially eight more highly specialized mini-computers on the same die. It's these SPEs that make the Cell architecture special, as you might guess. IBM describes the product as a 'System on a Chip.' Like IBM's Power5 processors, multi-processing is build right into the die.
