Abstract
Control over the overall data cache hit rate is obtained by managing partitioning caching responsibility by address space. Data caches determine whether to cache data by hashing the data address. Each data cache is assigned a range of hash values to serve. By choosing hash value ranges that do not overlap, data duplication can be eliminated if desired, or degrees of overlap can be allowed. Control over hit rate maximization of data caches having best hit response times is obtained by maintaining separate dedicated and undedicated partitions within each cache. The dedicated partition is only used for the assigned range of hash values.
