Abstract

The invention discloses a method for regulating operating frequency of a CPU (Central Processing Unit). The method comprises the following steps: determining tasks in a foreground running mode; determining a task type of tasks in the foreground running mode by utilizing a mapping relation between the prestored tasks and task type; determining the operating frequency of the CPU which corresponds to the task type by utilizing a mapping relation between the prestored task type and the operating frequency of the CPU; and configuring the operating frequency of the CPU by utilizing the operating frequency of the CPU which corresponds to the task type. According to the method for regulating operating frequency of the CPU, disclosed by the invention, the operating frequency of the CPU is configured according to the current task interacting with a user. Therefore, the influence of a background running task on the operating frequency of the CPU can be reduced, so that the operating frequency of the CPU is further reduced, the power consumption of the CPU is reduced, and the operating speed of the task interacting with the user is not influenced. Therefore, the user experience can still be guaranteed. The invention also discloses a device and a mobile terminal for regulating the operating frequency of the CPU.

Description

technical field [0001] The invention belongs to the technical field of CPU (Central Processing Unit) control, and in particular relates to a method, a device and a mobile terminal for adjusting the operating frequency of the CPU. Background technique [0002] At present, there are more and more mobile terminals, such as mobile phones and smart wearable devices. Since the capacity of the battery configured for the mobile terminal is limited, how to reduce the power consumption of the mobile terminal and prolong the battery life of the mobile terminal is a matter of great concern to various manufacturers. [0003] In a mobile terminal, the CPU consumes a large amount of power, and the power of the CPU is directly proportional to its operating frequency. Therefore, reducing the power consumption of the mobile terminal by adjusting the operating frequency of the CPU has become the current mainstream processing method. The current way of setting the operating frequency of the CP...
