Abstract
An apparatus for encoding/decoding an associative cache set use history, and method therefor, is implemented. A five-bit signal is used to fully encode a four-way cache. A least recently used (LRU) set is encoded using a first bit pair, and a second bit pair encodes a most recently used (MRU) set. The sets having intermediate usage are encoded by a remaining single bit. The single bit has a first predetermined value when the sets having intermediate usage have an in-order relationship in accordance with a predetermined ordering of the cache sets. The single bit has a second predetermined value when the sets having intermediate usage have an out-of-order relationship.
