Abstract
In an information processing apparatus, a control unit receives operation instructions. Each time receiving an operation instruction, the control unit detects the number of operating circuits that are to operate in accordance with the received operation instruction, in a circuit group of circuits that operate in synchronization with a clock signal. In addition, each time receiving an operation instruction, the control unit determines whether power supply noise that is likely to cause a timing error in the circuit group will occur, on the basis of a result of comparing an increase in the number of operating circuits per prescribed time period with a threshold, and lowers the frequency of the clock signal when determining that the power supply noise will occur.
