Abstract
Software assists a processor subsystem in making cache replacement decisions by providing an intermediary with information regarding how instructions and/or data of a working set are expected to be used and accessed by the software. The intermediary uses this information along with its knowledge of system requirements, policy and the cache configuration to determine cache usage and management hints for the working sets. The cache usage and management hints are passed by the intermediary to the processor subsystem.
