  • System and method for prefetching data into a cache based on miss distance
    Patent number: 6701414
    Abstract: A prefetcher to prefetch data for an instruction based on the distance between cache misses caused by the instruction. In an embodiment, the prefetcher includes a memory to store a prefetch table that contains one or more entries that include the distance between cache misses caused by an instruction. In a further embodiment, the addresses of data elements prefetched are determined based on the distance between cache misses recorded in the prefetch table for the instruction.
    Type: Grant

  • System and method for maintaining prefetch stride continuity through the use of prefetch bits
    Publication number: 20020087802
    Abstract: A processor includes a cache that has a lines to store data. The processor also includes prefetch bits each of which is associated with one of the cache lines. The processor further includes a prefetch manager that calculates prefetch data as if a cache miss occurred whenever a cache request results in a cache hit to a cache line that is associated with a prefetch bit that is set. In a further embodiment, the prefetch manager prefetches data into the cache based on the distance between cache misses for an instruction.
