The PowerPC 603 microprocessor: a high performance, low power, superscalar RISC microprocessor

Abstract

The PowerPC 603 microprocessor is the second member of the PowerPC microprocessor family. The 603 is a superscalar implementation featuring low power operation of less than 3 watts while maintaining high performance of 75 SPECint92 (estimated) at 80 MHz. The 7.4 mm by 11.5 mm design is implemented in 0.5 /spl mu/m, four-level metal CMOS technology. The 603 features dual 8-kByte instruction and data caches and a 32/64-bit system bus. Peak instruction rates of 3 instructions per clock cycle give outstanding performance to notebook and portable applications.> Author(s) Burgess, B.
