Abstract
A partitioned cache and management method for selectively caching data by type improves the efficiency of a cache memory by partitioning congruence class sets for storage of particular data types such as operating system routines and data used by those routines. By placing values for associated applications into different partitions in the cache, values can be kept simultaneously available in cache with no interference that would cause deallocation of some values in favor of newly loaded values. Additionally, placing data from unrelated applications in the same partition can be performed to allow the cache to rollover values that are not needed simultaneously.
