Aspects presented herein relate to methods and devices for data or graphics processing including an apparatus, e.g., a graphics processing unit (GPU). The apparatus may configure an address range in a cache. The apparatus may also obtain a request to access data in the cache, where the request to access the data includes an address in the cache that maps to a set index in a plurality of set indexes, where an address value for the set index corresponds to a portion of the address. Further, the apparatus may select an updated address value for the set index, where the updated address value is associated with an updated address within the address range, and the updated address value corresponds to a portion of the updated address. The apparatus may also allocate the data in the request to the updated address value for the set index.

Various embodiments include methods and devices for implementing a criterion aware cache replacement policy by a computing device. Embodiments may include updating a staling counter, writing a value of a local counter to a system cache in association with a location in the system cache for with data, in which the value of the local counter includes a value of the staling counter when (i.e., at the time) the associated data is written to the system cache, and using the value of the local counter of the associated data to determine whether the associated data is stale.
