Abstract

See full text

A data processing apparatus includes a requester, a completer and a cache. Data is transferred between the requester and the cache and between the cache and the completer. The cache implements a cache eviction policy. The completer determines an eviction cost associated with evicting the data from the cache and notifies the cache of the eviction cost. The cache eviction policy implemented by the cache is based, at least in part, on the cost of evicting the data from the cache. The eviction cost may be determined, for example, based on properties or usage of a memory system of the completer.
