Abstract:
A technology for supplying a power supply voltage to a microprocessor. Before normal arithmetic processing of the microprocessor, duty cycle correction process for adjusting the duty cycle of a clock signal inside the microprocessor is performed. In the duty cycle correction process for adjusting the duty cycle, the duty cycle of the clock signal is adjusted so as to minimize the power voltage at which the microprocessor is still operable.
