Abstract

See full text

A column-associative cache that reduces conflict misses, increases the hit rate and maintains a minimum hit access time. The column-associative cache indexes data from a main memory into a plurality of cache lines according to a tag and index field through hash and rehash functions. The cache lines represent a column of sets. Each cache line contains a rehash block indicating whether the set is a rehash location. To increase the performance of the column-associative cache, a content addressable memory (CAM) is used to predict future conflict misses.
