ABSTRACT:
A technique is provided for signaling to a first data processing circuit that an output of a second data processing circuit is ready for processing by the first data processing circuit. An occurrence of a logic transition at an input of the second data processing circuit is detected, and a latch circuit is used to produce a detection signal indicative of the occurrence. In response to the logic transition, the output of the second data processing circuit is produced, and this output is provided to the first data processing circuit. In response to production of the detection signal, and after delaying for an amount of time adequate to permit the second data processing circuit to produce its output, a done signal is sent to the first data processing circuit.
