Abstract
A mini-cache module is added to a computer system to increase throughput or may also be added to enhance the functionality of a general cache memory unit. The mini-cache module refills and stores frequently used data words concurrently during processor operations and provides them to the processor, eliminating the need to access a system bus to main memory. A data queue storage stores a data block of words from main memory and makes them available to requests from the main processor (if the requested address matches an address register block in the mini-cache). If an address 'hit' occurs, then the mini-cache will prevent any system bus request to main memory and additionally will monitor the system bus for any 'Write' operations which might feasibly change the validity of data in the data storage block of the mini-cache. In this case the data stored in the mini-cache is invalidated and cannot be used by the processor.
