Embodiment Construction

[0045] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail 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.

[0046] Such as figure 1 As shown, the method for controlling the operation of the central processing unit CPU in an embodiment includes step S120 to step S180.

[0047] Step S120, acquiring the load of each CPU core in a working state;

[0048] Step S140: It is judged whether at least one CPU core needs to be shut down currently;

[0049] Step S160, if yes, determine the CPU core to be shut down according to the load of each CPU core in the working state and the preset shut down rule;

[0050] Step S180, shut down the CPU core that needs to be shut down.

[0051] In the above-mentioned method for c...

Abstract

The invention relates to a method and device for controlling a central processing unit (CPU) to work. The method comprises the steps of obtaining a load of each CPU core in a working state; judging whether currently at least one CPU core needs to be shut down; if currently the at least one CPU core needs to be closed, determining the CPU cores needing to be shut down according to the load of each CPU core in the working state and preset shutting-down rules; and shutting down the CPU cores needing to be shut down. According to the method and device for controlling the CPU to work, work tasks of the CPU core can be optimized, and operation efficiency of the CPU is effectively improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for controlling the operation of a central processing unit (CPU). Background technique [0002] With the development of smart chips, in order to improve the computing power of smart chips, dual-core and multi-core chips have been widely used in smart devices, such as mobile terminals and PCs. [0003] In conventional operations, when dual-core and multi-core chips perform tasks, because different cores perform different tasks, the number of tasks performed is also different, resulting in different cores' current loads. When dual-core and multi-core chips are performing tasks, when the total load of the CPU cores is less than a certain threshold, it is necessary to stop the work of one or more CPU cores to facilitate the spare CPU cores to perform tasks that may need to be performed later . The conventional scheme is to stop the work of one or more CP...
