Abstract: The disclosed device includes a first register that stores a cumulative delta value and a second register that stores an average cache hit rate. The device also includes a control circuit that calculates a cache hit rate and updates the cumulative delta value based on the cache hit rate and the average cache hit rate. The control circuit also updates the average cache hit rate based on the updated cumulative delta value, and can update a cache allocation policy based on the updated average cache hit rate. Various other methods, systems, and computer-readable media are also disclosed.
