Read and Write Aware Cache

摘要

A mechanism is provided in a cache for providing a read and write aware cache. The mechanism partitions a large cache into a read-often region and a write-often region. The mechanism considers read/write frequency in a non-uniform cache architecture replacement polity. A frequently written cache line is placed in one of the farther banks. A frequently read cache line is place in one of the closer banks. The size ration between read-often and write-often regions may be static or dynamic. The boundary between the read-often region and the write-often region may be distinct or fuzzy.
