Abstract
An apparatus for performing data caching comprises at least one cache memory including multiple cache lines arranged into multiple segments, each segment having a subset of the cache lines associated therewith. The apparatus further includes a first plurality of counters, each of the counters being operative to track a number of active cache lines associated with a corresponding one of the segments. At least one controller included in the apparatus is operative to receive information relating to the number of active cache lines associated with a corresponding segment from the first plurality of counters and to implement a cache segment replacement policy for determining which of the segments to replace as a function of at least the information relating to the number of active cache lines associated with a corresponding segment.
