Abstract
An electric power measurement circuit includes: a period measurement circuit that measures a measurement period; a first measurer that measures (i) a first toggle number that is a number by which a signal value indicated by an input signal to a first target circuit has changed and (ii) a first operation period that is a period during which the input signal is valid; a second measurer that measures (i) a second toggle number that is a number by which a signal value indicated by an output signal from the first target circuit has changed and (ii) a second operation period that is a period during which the output signal is valid; and a calculator that calculates the first power consumption of the first target circuit based on the measured first toggle number, the measured first operation period, the measured second toggle number, and the measured second operation period.
