Linux embedded system-based dynamic power management method

Abstract

The invention provides a Linux embedded system-based dynamic power management method, which is implemented by a dynamic power management frame. The dynamic power management frame comprises a script layer, a virtual document interface layer, an equipment dynamic power management strategy layer and an equipment driving layer, wherein the script layer provides a script for controlling the dynamic power management frame; dynamic power management on specific equipment can be enabled / disabled through the script provided by the script layer; or the script layer acquires the relevant information about the equipment power management; the virtual document interface layer provides interfaces corresponding to script commands, and the interfaces are called by the script and comprise a virtual documentinterface of the whole dynamic power management frame and document interfaces of each power management equipment; the equipment dynamic power management strategy layer provides strategy interfaces ofeach power management equipment for the virtual document interface layer to call; and the equipment driving layer provides drive related to the dynamic power management of each power management equipment.

Description

technical field [0001] The invention belongs to the dynamic power management technology of an embedded system, in particular to a dynamic power management method based on a Linux embedded system. Background technique [0002] With the rapid development of semiconductor technology and the improvement of system integration and computing speed, the contradiction between high performance and low power consumption has become increasingly prominent. On the one hand, the rapid development of embedded technology and the widespread application of embedded devices have exposed some defects and deficiencies while providing convenience for people in communication and entertainment. The problem of energy consumption is a difficult point and a hot spot that people generally pay attention to in the design of embedded systems in recent years, and it seriously restricts the application and development of embedded systems. A large number of mobile systems are emerging, which are powered by b...

Problems solved by technology

The problem of energy consumption is a difficulty and hot spot that people generally pay attention to in the design of embedded systems in recent years, which seriously restricts the application and development of embedded systems

A large number of mobile systems are emerging, they are powered by batteries, and the batteries are strictly limited in weight and size

Especially for handheld devices, these devices are powered by batteries most of the time, and the battery power supply time is limited; and the structure is relatively compact, and the heat dissipation conditions are poor
