Abstract
An electronic apparatus includes a clock oscillator which supplies a clock signal, a processor which generates an internal clock on the basis of the clock signal supplied from the clock oscillator, and a control unit which controls a frequency of the internal clock in accordance with a ratio of an executable instruction count per unit time to a clock count per unit time of the internal clock generated by the processor.
