Abstract
A processor includes a core, a prefetcher, and a prefetcher control module. The prefetcher includes logic to make speculative prefetch requests through a memory subsystem for an element for execution by the core, and logic to store prefetched elements in a cache. The prefetcher control module includes logic to determine counts of memory accesses to two types of memory and, based upon the counts and the type of memory, reduce the speculative prefetch requests of the prefetcher.
