ABSTRACT:
A tag hit enable method for low power cache operation is provided which comprises inactivating all output buffers during all cache operations generating a tag hit enable signal, enabling/disabling dataram output buffers with said tag signal, activating only said output buffers receiving a hit state from a tag ram in order to transfer data from dataram to a CPU data bus, pre-charging said tag hit signals to tag miss signals, and disabling all data output buffers with said tag miss signals.
