Abstract
A method of prefetching from a memory device includes determining a prefetch buffer hit rate (PBHR) and a memory bandwidth utilization (MBU) rate. Prefetches are inserted aggressively if the memory bandwidth utilization (MBU) rate is above a MBU threshold level and the prefetch buffer hit rate (PBHR) is above a PBHR threshold level. Prefetches are inserted conservatively if the memory bandwidth utilization (MBU) rate is above the MBU threshold level and the prefetch buffer hit rate (PBHR) is below the PBHR threshold level.
