ABSTRACT:
A single chip cache address comparator with an on-chip static RAM for storing and checking the cache tags of an external cache memory. This cache address comparator has a built-in incrementing counter which controls the burst fill of the internal cache of a 68020/68030 microprocessor from the associated external cache memory within the required five processor clock cycles. Further, additional on-chip control logic is provided to control the 68020/68030 system buses to coordinate a burst fill operation.
