  • Split-cycle cache system with SCU controlled cache clearing during cache store access period
    Patent number: 4525777
    Abstract: In a cache memory unit including a cache directory identifying signal groups stored in an associated cache storage unit, apparatus and method are disclosed for searching the cache directory during a second portion of the cache memory cycle when the cache directory is not needed for normal operation, to determine if an invalid signal group is stored in the associated cache storage. When an invalid signal is found in the cache storage, this signal group is rendered unavailable to the data processing unit during the present cache memory cycle without interrupting the normal cache memory operation during succeeding cache memory cycles.
