ABSTRACT:
A computer system, a cache memory and a process, supporting prefetch operations and cache access operations so as to store information duplicated from a high level memory for use by a processing device, the processing device issuing addresses, including prefetch addresses and cache access addresses. The cache memory comprises memory resources, and prefetch resources are coupled to the memory resources and to the processing device both for receipt and storage of prefetch addresses from the processing device and for injection management of the received prefetch addresses so as to coordinate prefetch operations with cache access operations. As for the process, the invention comprises the steps of receiving prefetch addresses issued by a processing device; providing for storing, in a prefetch memory, prefetch addresses; and providing for injecting prefetch addresses in a selected order from the prefetch memory for use in fetching, into the cache memory, information associated with the prefetch addresses.
