The CELL , chip that is expected to challenge the dominance of Intel and Advanced Micro Devices, was unveiled yesterday by Sony, Toshiba and IBM at International Solid State Circuits Conference in San Francisco.

The CELL at a Glance:

CELL is a Multi-Core Architecture
· Contains 8 SPUs each containing a 128 entry 128-bit register file and 256KB Local Store
· Contains 64-bit Power ArchitectureTM with VMX that is a dual thread SMT design-views system memory as a 10-way coherent threaded machine
· 2.5MB of on Chip memory (512KB L2 and 8 * 256KB)
· 234 million transistors
· Prototype die size of 221mm2
· Fabricated with 90nanometer (nm) SOI process technology
· Cell is a modular architecture and floating point calculation capabilities can be adjusted by increasing or reducing the number of SPUs
CELL is a Broadband Architecture

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
