Abstract
A low-power synchronizer circuit, a data processing circuit that incorporates the synchronizer circuit, and a synchronization method are provided. The synchronizer circuit includes a delay circuit for receiving and delaying an asynchronous input signal, a first flip-flop having an input terminal connected to an output terminal of the delay circuit, a clock terminal for receiving the asynchronous input signal, and a reset terminal for receiving the asynchronous input signal, a synchronizer connected to an output terminal of the first flip-flop, and a clock-gating circuit for receiving a clock signal and determining whether to supply the clock signal to the synchronizer in response to one of a first output value of the delay circuit and a second output value of the first flip-flop and a third output value of the synchronizer.
