The CELL Supercomputer? The CELL is the most expected Processor as of today(10-Oct-05) in the market. The reasons for this? It is unlike anything before, and is expected tto last the current processor architecture cycle of just 6 years at max. Its developed so that a newer architecture won't be needed in the next 8-10 years. The CELL development was initiated by STI (Sony,Toshiba and IBM). As one might know Sony is the major hand behind Blue-Ray whereas Toshiba is behind HD-DVD. These giants are still clashing in the XBox 360 Vs. PlayStation 3. It would be a worthy battle hopefully between the XBox 360s' Xenon Vs. the CELL of PlayStation 3. Note: Both the processor have been developed by IBM. Architecturallly, both are In-order superscalar processors, and thats where the similarity ends. Xenon sports 3 identical PowerPC cores, and is more similar to the general purpose CPU's than CELL. The CELL is said to be extremely powerful threaded chip that is very much unconventional. First of all it features 1 PowerPC based core with 8 supporting SPE(Synergestic Processing Elements). PS3 is said to features at minimum 7 SPE. Speculation: Might be a problem with the yield? Each SPE is a very fast custom-DSP processor in itself. These SPE are connected via a circular bus. The PowerPC core is the so-called brain, which parallelizes and distributes the load among these 7-8 SPE's. There is much Documents and talk on CELL but everything is much speculative. Its definitive that SPE's can at a time decode multiple HD Channels, which a general purpose CPU will falter . The working in a OS based environment is highly anticipated. My view on it is, it would be a great processor for Parallel Processing an Indeed a great processor!!! It might not replace general purpose computers, but it will surely be the bread-butter of tomorrow's Super Computers. Links on CELL
