Design and implementation of the POWER5/spl trade/ microprocessor

Abstract

POWER5 offers /spl sim/4/spl times/ performance over the previous design by incorporating simultaneous multithreading, a latency-optimized memory subsystem, extensive reliability, availability and serviceability (RAS), and power management support. The 276M-transistor processor is implemented in a 0.13 /spl mu/m, 8M silicon-on-insulator technology and operates above 1.5 GHz.
