LIGHTWEIGHT PRIMARY CACHE REPLACEMENT SCHEME USING ASSOCIATED CACHE

摘要

One aspect provides an apparatus including: at least one processor; and a computer readable storage medium having computer readable program code embodied therewith and executable by the at least one processor, the computer readable program code including: computer readable program code configured to, responsive to a request for data and a miss in both a first cache and a second cache, retrieve the data from memory, the first cache storing at least a subset of data stored in the second cache; computer readable program code configured to infer from information available from the first cache a replacement entry in the second cache; and computer readable program code configured to, responsive to inferring from information available from the first cache a replacement entry in the second cache, replace an entry in the second cache with the data from memory. Other aspects are described and claimed.
