Abstract

The goal of this ASIC design was to produce a single-chip PC/AT-compatible controller optimized to perform in 80486SX- and 80486DX-based computer systems running at speeds of up to 33 MHz. Since VLSI has had five years experience with preceding designs for controllers for earlier microprocessors, a library of very large, high-performance `standard cells´ performing as functional system blocks (FSBs) were utilized. The resulting ASIC device provides reliable, predictable performance in the 486-based personal computer system environment
