Embodiment 1

[0039] Embodiment 1 of the CPU frequency control method of the present invention is applied to an electronic device that can run one or more application programs and has a processor. In Embodiment 1, when the electronic device detects that the When the running state of one or more applications changes, obtain the running state parameter corresponding to the running state change; based on the pre-stored correspondence data, match the processor frequency information corresponding to the running state parameter (such as CPU frequency ideal value), and adjust the operating frequency of the processor.

[0040] Specifically, in Embodiment 1, a change in the running state is reflected in the start, exit or suspension of one or more applications, such as figure 1 As shown, the method includes:

[0041] Step 101: Detect whether the application starts to run, exit or suspend, and obtain the detection result;

[0042] When the application program starts running, exits or pauses, the op...

example 1

[0043] Example 1: After the user turns on the game, he starts running the game application and thinks that the running status has changed;

example 2

[0044] Example 2: When a game application is currently running, a phone call is received, and the phone application starts running at this time. According to the system settings, for example, if only one application is running, the game application is suspended. At this time, the operating status changes ;

Abstract

The invention relates to a processor frequency control method and electronic equipment. The method is applied to the electronic equipment. One or more applications can run in the electronic equipment, and the electronic equipment is provided with a processor. The method comprises the steps of detecting whether a running state change occurs to the one or more applications or not to obtain a detection result; when the detection result indicates that the running state change occurs to the one or more applications, obtaining a running state parameter corresponding to the running state change; matching processor frequency information corresponding to the running state parameter based on pre-stored corresponding relation data; regulating the working frequency of the processor based on the processor frequency information. According to the processor frequency control method and the electronic equipment, the system performance of the electronic equipment during running can be improved.

Description

technical field [0001] The invention relates to electronic technology, in particular to a processor frequency control method and electronic equipment. Background technique [0002] In recent years, electronic devices such as personal computers (PCs), tablet computers (PADs), mobile phones, multimedia players, and personal digital assistants (PDAs) have become more popular. When an electronic device is running, it is a dynamic system. The programs executed inside it and its voltage and current will change continuously with the system running time, the size of the loading program and resource consumption, especially in big data processing such as image data processing and web browsing. When the amount of information is transmitted, the processor (CPU) must run at a higher frequency to meet the program requirements. At this time, the operating frequency of the CPU needs to be accelerated, but the speed of CPU frequency adjustment in the prior art is relatively slow, which bring...
