WRITE-ALLOCATION FOR A CACHE BASED ON EXECUTE PERMISSIONS

Systems and methods for managing access to a cache relate to determining one or more execute permissions associated with a write-address of a write-request to the cache. The cache may be a unified cache for storing data as well as instructions. If there is a write-miss in the cache for the write-request, a cache controller may determine whether to implement a write-allocate policy or a write-no-allocate policy for servicing the write-miss, based on the one or more execute permissions. The one or more execute permissions can relate to a privilege level associated with the write-address. Execute permissions of a producing agent which generated the write-request and an execute permission of a consuming agent which can execute from the write-address may be based on the privilege levels of the producing agent and the consuming agent, respectively.
