Abstract
A processor includes a core, a hardware prefetcher, and a prefetcher control module. The hardware prefetcher includes logic to make speculative prefetch requests, through a memory subsystem, for elements for execution by the core, and logic to store prefetched elements in a cache. The prefetcher control module includes logic to selectively suppress, based on a hardware-prefetch suppression instruction executed by the core, a speculative prefetch request to be made by the hardware prefetcher.
