In an information processing device including a processing circuit that performs processing in synchronization with a clock, and a clock supply control circuit that controls supply of the clock to the processing circuit, the number of cycles required from start of execution of processing in the processing circuit until output of a result of the processing is extracted, the extracted number of cycles is transferred to the clock supply control circuit, the supply of the clock is started when the processing is started in the processing circuit, and the supply of the clock to the processing circuit is stopped when the supply of the clock with the number of cycles is completed. Thus, a clock control method and an information processing device employing the clock control method are provided that allow power consumption to be reduced without impairing an execution efficiency of pipeline processing.
