Abstract: A technique for generating an appropriate clock is provided. A clock generation circuit generates a logic-circuit clock on the basis of a reference clock and outputs the logic-circuit clock to a logic circuit. The clock generation circuit and the logic circuit are both supplied with power from a power supplier. According to a control signal from a power controller, the power supplier changes a power voltage value provided to the clock generation circuit and the logic circuit. The control signal is generated by the power controller on the basis of a counter value from the clock generation circuit. The counter value is obtained from a digital counter which determines the delay speeds of delay elements in a multiplier circuit in the clock generation circuit.
