A 0.2μm 1.8V SOI 550MHz 64b PowerPC microprocessor with copper interconnects

摘要

A 64b PowerPC RISC microprocessor is incorporated in a 0.2μm CMOS technology with copper interconnects and multi-threshold transistors and next into a silicon-on-insulator (SOI) version of the same technology [1, 2]. Some architectural changesimprove CPI, including doubling the L1 instruction and data caches to 128kB and adding a 256kB L2 directory. The total transistor count increased from 12M to 34M.
