Abstract :
A 90-MHz CMOS CPU has been designed for sustained performance in workstation and commercial/technical multiuser applications. The CPU is part of a multichip system that achieves a 60-MHz operating frequency with 15-ns asynchronous SRAMs. Key performance features include a 3.5-ns 32-b adder, low skew on-chip clock buffers, and cycling large off-chip caches at the operating frequency. The chip has been fabricated using a 1.0-μm CMOS process that utilizes three-level metal and 480000 transistors on a 14×14-mm die
