Embodiment Construction

[0048] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0049] figure 1 It is a flow chart of the first embodiment of the method for adjusting the CPU frequency of the mobile terminal 100 of the present invention, as figure 1 Shown, method of the present invention comprises the following steps:

[0050] S1. Configuring CPU frequency adjustment strategies for different system scenarios of the mobile terminal 100 respectively;

[0051] S2. Determine the current system scenario of the mobile terminal 100;

[0052] S3. Adjust the frequency of the CPU according to the CPU frequency adjustment strategy corresponding to the current system scenario.

[0053] In this embodiment, system scenarios may be divided according to power consumption or currently used modules. When using power consumption to divide system scenarios, for example, it can be divided into three types of system scenarios, the first type is low ...

Abstract

The invention discloses a mobile terminal and a method for adjusting the CPU frequency thereof. The mobile terminal comprises a strategy configuration unit, a system scene determination unit and a frequency adjustment unit. The method includes S1, configuring CPU frequency adjustment strategies for different system scenes of the mobile terminal respectively; S2, determining the current system scene of the mobile terminal; S3, adjusting the CPU frequency according to the CPU frequency adjustment strategy corresponding to the current system scene. The mobile terminal and the method for adjusting the CPU frequency thereof can be used for automatically switching the CPU frequency adjustment strategies for the different system scenes, so that system scenes of low power consumption can be applied with a conservative frequency adjustment strategy, and system scenes of high performance requirement and high power can be applied with an active frequency adjustment conservative strategy. Therefore, the power consumption is reduced and the battery life of the mobile terminal is prolonged.

Description

technical field [0001] The invention relates to a method for controlling CPU frequency, more specifically, a mobile terminal and a method for adjusting its CPU frequency. Background technique [0002] With the rapid development of mobile terminals (for example, smart phones), such as the application of multi-core processors, the performance of mobile terminal processors is getting better and better, but the power consumption of mobile terminals is also increasing, resulting in the battery life of mobile terminals become shorter. [0003] The CPU does not run at one frequency all the time, but runs at different frequencies according to actual needs, so as to achieve the goal of optimal power consumption and performance. The higher the CPU frequency, the greater the relative power consumption. In the current technology, the frequency adjustment of the CPU is realized through a dynamic voltage frequency scaling (DVFS, Dynamic Voltage and Frequency Scaling) strategy. Specifica...
