Digital circuit energy consumption optimization method

Abstract

The invention discloses a digital circuit energy consumption optimization method, which combines the characteristics that the energy consumption in a digital circuit mainly comes from dynamic energy consumption and the dynamic energy consumption is dominated by the flipping rate of the digital circuit, and considers that the flipping rate of the digital circuit is closely related to an actual input data sequence. And estimating the flipping rate of the digital circuit according to the probability distribution of the input data sequence, and taking the flipping rate as a basis for judging the energy consumption of the digital circuit. By analyzing the probability distribution of the data sequence, the energy consumption of the digital circuit can be accurately estimated, a data basis is provided for optimizing the operation sequence of the data sequence, and the operation sequence of the data sequence is dynamically optimized by estimating the flipping rate when the digital circuit inputs different operation sequences of the data sequence in real time. Therefore, the energy consumption of the digital circuit is reduced.
