APPARATUS AND METHOD OF PREFETCHING DATA

摘要

A device (300) and method is illustrated to prefetch information based on a location of an instruction that resulted in a cache miss during its execution. The prefetch information to be accessed is determined based on previous and current cache miss information. For example, information based on previous cache misses is stored at data records as prefetch information. This prefetch information includes location information based on an instruction that caused a previous cache miss, and is accessed to generate prefetch requests for a current cache miss. The prefetch information is updated based on current cache miss information.
