ABSTRACT:
A clock selection circuit and method may operate to generate a clock signal for a digital processing system. In the clock selection circuit, first and second clock control signals may be generated based on a received control signal and/or the inverse of a received clock signal. A first clock signal may be selected when the first clock control signal is activated, and may be output as the selected clock signal. A second clock signal may be selected when the second clock control signal is activated, and may be output as the selected clock signal. The selection operation of the clock selection circuit may reduce the likelihood that a glitch occurs and/or may reduce the amount of power consumed when compared to a conventional clock selection circuit.
