Embodiment Construction

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Since the input data sequence is closely related to the power consumption of the digital circuit, for the same input data sequence, different operation sequences will lead to different power consumption of the digital circuit. In order to reduce the energy consumption of the digital circuit and discuss the relationship between the energy consumption of the digital circuit and the operation or...

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.

Description

technical field [0001] The invention belongs to the field of digital circuits, and more particularly, relates to a method for optimizing energy consumption of digital circuits. Background technique [0002] With the commercial deployment of fifth-generation mobile communication systems, global mobile data traffic has shown an exponential growth trend. Massive data processing will lead to a large amount of energy consumption and greenhouse gas emissions, aggravating global warming. The rising energy consumption will seriously hinder the energy saving and emission reduction of the digital communication system and the green and healthy development of the information and communication industry in the future. In order to reduce the energy consumption of the digital communication system and promote the green and healthy development of the information and communication industry, the digital circuit as the physical carrier of the digital communication system faces the challenge of ...
