摘要：A computer-implemented method for cache memory management includesreceiving a coherence request message from a requesting processor. The method canfurther include determining a request type responsive to detecting the transactional
conflict. The request type is indicative of whether the coherence request is a prefetchrequest. The method further includes detecting, with a conflict detecting engine, atransactional conflict with the coherence request message. The method further includessending, with the adaptive prefetch throttling engine, a negative acknowledgement tothe requesting processor responsive to a determination that the coherence request is aprefetch request.
