ABSTRACT:
A request tracking data prefetch apparatus for a computer system is described. The apparatus includes a prefetcher coupled to a memory of the computer system. A tracker is coupled to the prefetcher, and is configured to recognize an access to a plurality of cache lines of the memory by a processor of the computer system. A cache memory is coupled to the prefetcher. The prefetcher predictively loads a target cache line of the memory into the cache memory. The target cache line for the predictive load is indicated by the tracker.
