A CMOS RISC CPU with on-chip parallel cache

Abstract

This CMOS CPU in a 0.55 /spl mu/m, 3-metal process integrates over 1.2 M transistors on a single chip. All circuitry on-chip operates at 140 MHz under typical conditions. All off-chip interfaces are cycled at the same frequency (with the exception of system bus interface, which is cycled at 120 MHz). Chip parameters are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
