Performance By Retaining High Locality Data In Higher Level Cache Memory

摘要

Various aspects include methods for implementing retaining high locality data in a higher level cache memory on a computing device. Various aspects may include receiving a cache access request for a first cache line in the higher level cache memory indicating a locality of the first cache line, determining whether the access request indicates high locality, and setting a high locality indicator of the first cache line in response to determining that the cache access request indicates high locality. Various aspects may include determining whether a lower level cache memory hit counter of a first cache line of a first cache exceeds a lower level cache locality threshold, setting a high locality indicator of the first cache line in response to determining that the lower level cache memory hit counter exceeds the lower level cache locality threshold and resetting the lower level cache memory hit counter of the first cache.
