Webaggressiveness of the hardware prefetcher is decreased or in-creased dynamically. Also, based on the run-time estimation of the cache pollution caused by the prefetcher, the proposed mechanism dynamically decides where to insert the prefetched blocks in the processor cache’s LRU stack. Our results show that using the proposed dynamic feed- WebNov 6, 2024 · Hardware prefetcher does exactly that.
