Abstract

A method for dynamic frequency modulation method and device, an apparatus and a storage medium are disclosed. By using the frequency value of the frequency closest to the requested frequency value inthe frequency list of the hardware platform as the target frequency value, then, combining with the running time of the target frequency value, the frequency of the processor CPU is set to the corresponding target frequency value, so that the average running frequency value of the processor CPU can be equal to the request frequency value, thereby achieving the purpose of saving the power consumption of the processor CPU of the mobile terminal equipment and reducing the heat generation of the system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a dynamic frequency modulation method, device, equipment and storage medium. Background technique [0002] With the development of technology, the processing capacity of the processor CPU is getting higher and higher. At present, most of the processor CPUs of smart phones can already work above 1.5GHz, and the higher the main frequency of the mobile terminal device processor CPU, the higher the power consumption of the system. However, on mobile terminal devices such as smart phones, it is not necessary to make the processor CPU work at the highest main frequency all the time. Most of the time, the processor CPU can work under a light load state. [0003] In order to save power consumption of the processor CPU of the mobile terminal device and reduce system heat generation, an appropriate main frequency can be dynamically configured for the processor CPU according to the curre...
