The design of an asynchronous clone of a MIPS R3000 microprocessor is presented. In 0.6 /spl mu/m CMOS, we expect performance close to 280 MIPS, for a power consumption of 7 W. The paper describes the structure of a high-performance asynchronous pipeline, in particular precise exceptions, pipelined caches, arithmetic, and registers, and the circuit techniques developed to achieve high throughput.
