摘要
A method and apparatus for selecting and updating a replacement candidate in a cache is disclosed. In one embodiment, a cache miss may initiate the eviction of a present replacement candidate in a last-level cache. The cache miss may also initiate the selection of a future replacement candidate. Upon the selection of the future replacement candidate, the corresponding cache line may be invalidated in lower-level caches but remain resident in the last-level cache. The future replacement candidate may be updated by subsequent hits to the replacement candidate in the last-level cache prior to a subsequent cache miss.
