Abstract

A cache system which includes prefetch pointer fields for identifying lines of memory to prefetch thereby minimizing the occurrence of cache misses. This cache structure and method for implementing the same takes advantage of the previous execution history of the processor and the locality of reference exhibited by the requested addresses. In particular, each cache line contains a prefetch pointer field which contains a pointer to a line in memory to be prefetched and placed in the cache. By prefetching specified lines of data with temporal locality to the lines of data containing the prefetch pointers the number of cache misses is minimized.
