An apparatus comprises a set-associative cache comprising a plurality of sets of cache entries, and cache replacement policy storage circuitry to store a plurality of local replacement policy entries. Each local replacement policy entry comprises local replacement policy information specific to a corresponding set of the set-associative cache. Cache control circuitry controls replacement of cache entries of the set-associative cache based on the local replacement policy information stored in the cache replacement policy storage circuitry. The cache replacement policy storage circuitry stores local replacement policy entries for a proper subset of sets of the set-associative cache.
