ABSTRACT:
A two-level storage hierarchy for a data processing system is directly addressable by the main processor. The two-level storage includes a high speed, small cache with a relatively slower, much larger main memory. The processor requests data from the cache and when the requested data is not resident in the cache, it is transferred from the main memory to the cache and then to the processor. The data transfer organization maximizes the system throughput and uses a single integrated control to accomplish data transfers.
