POWER CONSUMPTION CALCULATING DEVICE, ITS METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To enable to calculate power consumption with high precision by respectively storing the obtained value of power consumption in a two-dimensional power consumption table consisting of the value of an output load capacity and input waveform rounding values (respective index values) by means of correspondence. SOLUTION: The reference value P0 of a power which is consumed inside a circuit regardless of an input waveform rounding x and the output load capacity y is obtained (S16). Power consumption P1(x) depending on the input waveform rounding x is obtained and these kinds of power consumption P1(x) are outputted to an output device as a power consumption table concerning an input terminal (S17). Power consumption P2(y) depending on the output load capacity (y) is obtained among powers to be consumed in the circuit (S18). Since the component of P0 is included in the both of P1(x) and P2(y), the value of an equation: P3(y)=P2(y)-P0 is outputted to the output device as the power consumption table concerning the input terminal (S19) in order to prevent the superimposed sum-up of the portion of P0.
