A study of cache hashing functions for symbolic applications in micro-parallel processors

Abstract

This paper presents a study of cache hashing functions for micro-parallel processors (e.g., superpipeline and super-scalar processors). Several novel cache hashing functions are experimented. Our simulation results show that an unconventional cache hashing function applied on a direct-mapped cache results in hit rates as good as a two-way set associative cache with traditional mapping, while the cache hit times are as fast as a direct-mapped cache with traditional mapping.
