Title: NO ALLOCATE CACHE POLICY
Abstract:
A system and method for efficiently performing data allocation in a cache memory are described. A lookup is performed in a cache responsive to detecting an access request. If the targeted data is found in the cache and the targeted data is of a no allocate data type indicating the targeted data is not expected to be reused, then the targeted data is read from the cache without updating cache replacement policy information for the targeted data responsive to the access. If the lookup results in a miss, the targeted data is prevented from being allocated in the cache.
