摘要
Adaptive cache prefetching based on competing dedicated prefetch policies in dedicated cache sets to reduce cache pollution is disclosed. In one aspect an adaptive cache prefetch circuit is provided for prefetching data into a cache. The adaptive cache prefetch circuit is configured to determine which prefetch policy to use as a replacement policy based on competing dedicated prefetch policies applied to dedicated cache sets in the cache. Each dedicated cache set has an associated dedicated prefetch policy used as a replacement policy for the given dedicated cache set. Cache misses for accesses to each of the dedicated cache sets are tracked by the adaptive cache prefetch circuit. The adaptive cache prefetch circuit can be configured to apply a prefetch policy to the other follower (i.e. non dedicated) cache sets in the cache using the dedicated prefetch policy that incurred fewer cache misses to its respective dedicated cache sets to reduce cache pollution.
