Abstract
A processor includes a prefetcher that prefetches data in response to memory accesses, wherein each memory access has an associated memory access type (MAT) of a plurality of predetermined MATs. The processor also includes a table that holds scores that indicate effectiveness of the prefetcher to prefetch data with respect to the plurality of predetermined MATs. The prefetcher prefetches data in response to memory accesses at a level of aggressiveness based on the scores held in the table and the associated MATs of the memory accesses.
