  • Data processor with cache and method of operation
    Patent number: 5809532
    Abstract: A data processor (10) has a data cache (16) that supports snooping operations and conserves power. A freeze logic unit (46) enables the data cache when the data cache performs a load/store operation from an execution unit (24) or when it detects a snoop operation. However, the freeze logic unit disables all clock regenerators (44) coupled to the data cache while the data cache waits for data to be returned to it from a common memory system after a data "miss.
