Abstract
Systems and methods for tracking cache line consumption. An example system may comprise: a cache comprising a plurality of cache entries for storing a plurality of cache lines; a processing core, operatively coupled to the cache; and a cache control logic, to: responsive to detecting an update operation with respect to a cache line of the plurality of cache lines, set a cache line access tracking flag associated with the cache line to a first state indicating that the cache line has been produced; and responsive to detecting a read operation with respect to the cache line, set the cache line access tracking flag associated with the cache line to a second state indicating that the cache line has been consumed.
