Abstract
One embodiment of the present invention provides a system for mapping memory addresses to cache entries. The system operates by first receiving a memory request at the cache memory, wherein the memory request includes a memory address. The system then partitions the memory address into a set of word offset bits and a set of higher-order bits. Next, the system maps the memory address to a cache entry by computing a modulo operation on the higher-order bits with respect to an integer and using the result as the cache index.
