Abstract
An apparatus for detecting an edge timing of an input signal and operating on the basis of the edge timing while power consumption thereof is reduced. The apparatus includes an edge detecting circuit that detects edges of an input signal to generate an edge timing representing signal representative of edge timings of the edges, a signal processing circuit responsive to the edge timing representing signal. The edge detection circuit outputs an enable signal to enable the signal processing circuit to operate when the edge detection circuit finds one of the edges. The signal processing circuit executes a signal processing of the edge timing representing signal in response to the enable signal.
