Abstract
A method of choosing a cache line of a plurality of cache lines of data for eviction from a frontend memory, the method including assigning a baseline replacement score to each way of a plurality of ways of a cache, the ways respectively storing the cache lines, assigning a validity score to each way based on a degree of validity of the cache line stored in each way, assigning an eviction decision score to each way based on a function of the baseline replacement score for the way and the validity score for the way, and choosing a cache line of the way having a highest eviction decision score as the cache line for eviction.
