Abstract:
A cache memory eviction method includes maintaining thread-aware cache access data per cache block in a cache memory, wherein the cache access data is indicative of a number of times a cache block is accessed by a first thread, associating a cache block with one of a plurality of bins based on cache access data values of the cache block, and selecting a cache block to evict from a plurality of cache block candidates based, at least in part, upon the bins with which the cache block candidates are associated.
