Abstract
Systems and methods for providing data from a cache memory to requestors includes a number of cache memory levels arranged in a hierarchy. The method includes receiving a request for fetching data from the cache memory and determining one or more addresses in a cache memory level which is one level higher than a current cache memory level using one or more prediction algorithms. Further, the method includes pre-fetching the one or more addresses from the high cache memory level and determining if the data is available in the addresses. If data is available in the one or more addresses then data is fetched from the high cache level, else addresses of a next level which is higher than the high cache memory level are determined and pre-fetched. Furthermore, the method includes providing the fetched data to the requestor.
