Handshake circuit and operating method for self-resetting circuits

摘要

In a circuit that generates a plurality of dynamic signals in a self-resetting signal path, none of which may occur in some cycles, a handshake circuit generates a signal indicative of whether none of the signals occurred and incorporates the plurality of dynamic signals and the signal indicative that none of the signals occurred into a handshake signal. The handshake circuit generates a "normal operation" signal designating that one of the plurality of dynamic signals occurred. The handshake circuit also generates a "reset" signal indicative that none of the signals occurred.
