Abstract: Provided are methods, systems, and apparatus for managing and controlling memory caches, in particular, system level caches outside of those closest to the CPU. The processes and representative hardware structures that implement the processes are designed to allow for detailed control over the behavior of such system level caches. Caching policies are developed based on policy identifiers, where a policy identifier corresponds to a collection of parameters that control the behavior of a set of cache management structures. For a given cache, one policy identifier is stored in each line of the cache.
