Zusammenfassung:A method, system, and processing system for pre-fetching data is disclosed. The method, system, and processing system includes data cache region prefetch circuitry for detecting a first access by a first instruction at a first instruction address to a first memory portion, detecting a first non-sequential access pattern to a set of addresses in the first memory portion, and in response to a miss by a second instruction at the first instruction address, and in response to the non-sequential access pattern occurring, pre-fetching data according to the first non-sequential access pattern.
