PROBLEM TO BE SOLVED: To provide a power saving control device for, when a speed control interval is longer than the operation time of power saving control, achieving the shift/release of a power saving mode in the speed control of a processor, and for suppressing an error which occurs in the shift/release period of the power saving mode.SOLUTION: The power saving control device for performing power saving control of a specific circuit during the speed control processing of a processor is configured to, when a speed control interval is longer than the operation time of the power saving control, shift a mode to a power saving mode for suppressing the power consumption of the specific circuit. Furthermore, the power saving control device includes an error control part for performing control to suppress an error which occurs in the shift/release period of the power saving mode in the specific circuit. |
