摘要：
The information processing apparatus equipped with a microprocessor is provided. The information processing apparatus equipped with a microprocessor includes: an operation clock signal generator that generates a frequency-variable operation clock signal supplied to the microprocessor; and a power supply voltage generator that determines a value of a power supply voltage to be supplied to the microprocessor according to a logarithm of a frequency of the operation clock signal and generates the power supply voltage.
