DATA CACHE PREFETCH HINTS

摘要

The present disclosure provides a method and apparatus for using prefetch hints. One embodiment of the method includes bypassing at a first prefetcher (150) associated with a first cache (120) issuing requests to prefetch data from a number of memory addresses in a sequence of memory addresses determined by the first prefetcher. The number is indicated in a request received from a second prefetcher (140) associated with a second cache (125). This embodiment of the method also includes issuing from the first prefetcher a request to prefetch data from a memory address subsequent to the bypassed memory addresses.
