PROBLEM TO BE SOLVED: To stop supply of a clock to a second computation means, in an information-processing device, when the start-up processing of the second computation means is completed during operation of a first computation means.SOLUTION: A DSP 203 shifts the DSP 203 to an interruption waiting state after DSP 203 start-up processing is completed (S204). When the DSP 203 shifts to the interruption waiting state, the DSP 203 stops the supply of a clock to the DSP 203 by using a clock-controlling part 310 (S205). When receiving an interruption signal from a CPU 201, the DSP 203 resumes the supply of the clock to the DSP 203 by using the clock-controlling part 310 (S207). The DSP 203 restores the DSP 203 from the interruption waiting state (S209). |
