Method for realizing low power consumption of electric terminal

Abstract

The invention provides a method for realizing low power consumption of an electric terminal. The method comprises the following steps: A, electrifying the terminal, and electrifying and initializing function modules; B, initializing parameters of a low-power-consumption model and monitoring the state and the electric quality of the terminal; C, judging whether the function modules need to work continually or not by a core plate; D, comparing residual electric quality with electric quality calculated by the model to obtain electric quality deltaE consumed by time deltat; E, controlling a power switching-on / off circuit of the corresponding function module which does not need to work by a low electric level signal output by a GPIO (General Purpose Input / Output) port and switching off the power supply of the module; otherwise, controlling the power switching-on / off circuit of the corresponding module by a high electric level signal output by the GPIO port and switching on the power supply of the module; and F, repeating the steps until all the modules are at an idle state. The method does not depend on information of system parameters and has strong adaptability; potentials or other related quantities of all the states do not need to be calculated, and a calculation amount and a needed storage space are small so that the instantaneity of an algorithm can be effectively improved; the method has overall convergence, the inherent limitation of a gradient method is overcome and the application effect of the algorithm is guaranteed.

Description

technical field [0001] The invention relates to low power consumption estimation and design technology of battery-powered equipment terminals, such as mobile computing, mobile communication, multimedia equipment and the like. It specifically involves a modular design of the terminal in the design of the power metering monitoring terminal. Each module adopts a distributed power supply that can be controlled to be disconnected, and the power supply is turned off by controlling the modules that are not put into operation during the actual operation of the terminal. Thereby reducing the method of terminal power consumption. Background technique [0002] As the scale of integrated circuits shrinks day by day and the complexity of circuit systems increases further, especially with the development of SOC (System On a Chip) technology and the wide application of battery-powered mobile devices, chip power consumption has become a major issue in the field of integrated circuit design....

AI Technical Summary

Problems solved by technology

Mobile devices (such as mobile phones, handheld computers, mobile multimedia, and some special applications such as cardiac pacemakers, etc.) cannot be equipped with oversized cooling devices, and the capacity of mobile power is also very limited, so low power consumption technology is particularly important

[0004] The power consumption of integrated circuits not only affects the cost of the circuit system to a large extent, affects the reliability and stability of the circuit, but also directly affects its application prospects in certain fields.
