Abstract

The invention provides a power consumption management method and apparatus, and an electronic device, relates to the technical field of power consumption control, and solves the problem of relativelyhigh system power consumption or low stability of power consumption control in the prior art. The power consumption management method comprises the steps of obtaining states of threads in a process running in a current system; according to the states of the threads in the process running in the current system, judging current load states of a CPU and a GPU; and according to the current load statesof the CPU and the GPU, performing dynamic adjustment on the frequencies of the CPU and / or the GPU. The power consumption management method and apparatus is suitable for control of the system power consumption in the electronic device.

Description

technical field [0001] The present invention relates to the technical field of power consumption control, in particular to a power consumption management method, device and electronic equipment. Background technique [0002] In embedded platforms, there are strict requirements for power consumption control, especially in smart devices, each application may be different due to the design of the program, and there is no control over the CPU (Central Processing Unit, central processing unit) and GPU. (Graphics Processing Unit, graphics processing unit) frequency is adjusted, resulting in very serious power consumption. Even though some embedded platforms have implemented dynamic power consumption management for the CPU, which can reduce the frequency at a certain stage, or even hibernate and standby, but it is not enough. Before the emergence of new battery technologies, the overall power consumption of the system can only be reduced through more reasonable management of power...
