Abstract:
Disclosed embodiments relate to a prefetcher for delinquent irregular loads. In one example, a processor includes a cache memory, fetch and decode circuitry to fetch and decode instructions from a memory; and execution circuitry including a binary translator (BT) to respond to the decoded instructions by storing a plurality of decoded instructions in a BT cache, identifying a delinquent irregular load (DIRRL) among the plurality of decoded instructions, determining whether the DIRRL is prefetchable, and, if so, generating a custom prefetcher to cause the processor to prefetch a region of instructions leading up to the prefetchable DIRRL.
