Abstract: A processing device comprises a processing device cache and a cache controller. The cache controller initiates a cache line eviction process and determines determine an object liveness value associated with a cache line in the processing device cache. The cache controller applies the object liveness value to a cache line eviction policy and evicts the cache line from the processing device cache based on the object liveness value and the cache line eviction policy.
