Abstract
In accordance with the described techniques, a processor includes a cache system having a level two cache, and a hardware prefetcher associated with the level two cache. The hardware prefetcher monitors a workload that includes accesses to the level two cache, and measures a degree of thrashing exhibited by the workload in the level two cache based on the accesses. Prefetch requests issued by the hardware prefetcher are throttled based on the degree of thrashing being greater than or equal to a thrashing threshold.
