Abstract

Performance of a cache memory may be improved by allowing cache entries for multiple processes to reside in the cache concurrently. When a context switch occurs, the cache does not need to be automatically flushed of all entries, If the cache is large enough, upon returning to a process, cache entries for that process may still be resident. By allowing cache entries to remain in the cache across context switches, the hit rate of the cache increases.
