Abstract

We investigate potential advantages and problems when a superscalar processor is designed and implemented using asynchronous design methods. Conventional techniques of superscalar processing are applied and data dependent adder is considered as an asynchronous component. Intensive simulations on SPEC INT95 benchmark suites are made for the purpose of performance comparison between a synchronous and an asynchronous superscalar processor, respectively. The simulation results show about 5% speedup with asynchronous design methods in the sense of Issue Rate.
