Problems solved by technology

However, playing audio and video does not always require the highest operating frequency of the CPU, which will consume more power and increase the load on the CPU
[0004] The disadvantage of the above-mentioned technical solution is that the load of the CPU is increased and the power consumption is increased.

Embodiment Construction

[0051] An embodiment of the present invention provides a control method for a central processing unit, such as figure 1 shown, including:

[0052] 101: During the running of the application program, determine the amount of data to be processed by the above application program;

[0053] The above-mentioned application programs run on terminal devices such as mobile phones, tablet computers, personal digital assistants (Personal Digital Assistant, PDA), mobile Internet devices (Mobile Internet Device, MID), and sales terminals (Point of Sales, POS). The above-mentioned application programs may be various application programs such as music player programs, video player programs, and games. The above-mentioned amount of data to be processed may be the data processing rate required by the above-mentioned application program at the next moment, that is, the amount of data to be processed per second, and may also be understood as the resources of the central processing unit required...

Abstract

The embodiment of the invention discloses a control method of a central processing unit and terminal equipment. The method comprises the steps that the to-be-processed data volume of an application program is determined in the running process of the application program; whether the to-be-processed data volume is larger than a first preset threshold value or not is judged; if yes, the number and / or the working frequency of running cores of the central processing unit is increased. When the to-be-processed data volume of the application program of the terminal equipment is larger than the first preset threshold value, the number and / or the working frequency of the cores of the central processing unit is increased; when the to-be-processed data volume of the application program of the terminal equipment is smaller than the first preset threshold value, the working frequency of the central processing unit keeps invariable. According to the scheme, electricity consumption can be reduced, and the running smoothness of the application program can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method of a central processing unit and a terminal device. Background technique [0002] With the rapid development of terminal equipment (such as smart phones, desktop computers, and tablet computers, etc.), multi-core processors are widely used in terminal equipment, making the performance of terminal equipment processors better and better. Correspondingly, terminal equipment The power consumption of the terminal equipment also increases accordingly, which in turn shortens the battery life of the terminal equipment. [0003] The central processing unit (Central Processing Unit, CPU) in the terminal device does not always run at one frequency, but will adjust the frequency according to actual needs, so that the CPU runs at different frequencies, so as to achieve the purpose of optimal power consumption and performance . At present, the working mode in ...
