Abstract

Embodiments of the invention disclose a method for controlling CPU power consumption. The method comprises: detecting a screen refresh rate FPS of a display thread; acquiring a processor core corresponding to the display thread; adjusting a running frequency of the processor core corresponding to the display thread according to the FPS of the display thread; and detecting the running frequency of the processor core, and when it is detected that the running frequency of the processor core is greater than a threshold value, adding a new processor core to the display thread. In addition, embodiments of the invention further disclose an apparatus for controlling the CPU power consumption. By virtue of the method and apparatus disclosed by the embodiments of the invention, terminal power consumption can be reduced.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a method and device for controlling CPU power consumption. Background technique [0002] With the continuous development of processor technology, multi-core technology has become an important direction for the development of today's processors. Compared with the traditional single-core chip, the multi-core processor technology can greatly improve the performance of the system while keeping the frequency constant through the mutual assistance of multiple processing cores. [0003] For the display content displayed on the display interface of the terminal, the display content consists of multiple different modules or areas, and different foreground applications are responsible for the display content of different areas or modules. For example, the signal bar application is responsible for updating the signal display, battery The control module is responsible for updating the batte...
