ABSTRACT:
A processing system has a processor, a cache, and a fetch unit. If there is a miss in the cache, the fetch unit generates a fetch address for the miss in the cache for the purpose of retrieving the requested data from external memory and providing the data to the processor and loading the data in a location in a line in the cache. The fetch unit also generates additional prefetch addresses for addresses consecutive with the fetch address. The prefetch addresses continue to be generated for all of the locations in the line in the cache that are consecutive with the fetch address. The generation of prefetch addresses will be stopped if another requests arrives that is not part of the already generated prefetched addresses. Further, the outstanding prefetches will be terminated if the external memory can handle such termination.
