Problems solved by technology

[0003] In related technologies, frequency modulation methods mainly include two types: the first is unified frequency modulation at the system level, and tasks running on the CPU are accelerated (when frequency is increased) or decelerated (when frequency is decreased). Obviously, this method is targeted Poor, so that some tasks that do not need to be frequency-regulated are also frequency-regulated, resulting in waste of resources; the second is to perform frequency regulation from the task level, and only perform frequency regulation for tasks that require frequency regulation. However, there is a lag problem between frequency regulation and task operation in related technologies. As a result, the frequency adjustment time is later than the actual running time of the task, and the task has not been effectively optimized for frequency adjustment

Abstract

The invention provides a frequency modulation method, a frequency modulation device, a storage medium and an electronic device, and relates to the technical field of computers. The method comprises the steps of detecting a current state of a fast frequency modulation mode in response to the fact that a to-be-run task group meets a preset state; when the fast frequency modulation mode is an open state, calling a preset real-time frequency modulation thread to perform frequency modulation according to the task in the running queue; and when the fast frequency modulation mode is a closed state, calling a native scheduler to perform frequency modulation according to the load parameters of the to-be-operated task group. According to the present invention, the problem of hysteresis of frequencymodulation in the related technologies can be solved, the pertinence and timeliness of the frequency modulation are improved, the actual acceleration effect on the task operation after frequency modulation is improved, and the method and the device have the relatively higher flexibility.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and in particular to a frequency modulation method, a frequency modulation device, a computer-readable storage medium, and electronic equipment. Background technique [0002] Frequency modulation refers to adjusting the operating frequency of a processor on an electronic device, including frequency modulation of a CPU (Central Processing Unit, central processing unit), GPU (Graphics Processing Unit, graphics processing unit), etc., to improve performance or reduce power consumption. [0003] In related technologies, frequency modulation methods mainly include two types: the first is unified frequency modulation from the system level, and tasks running on the CPU are accelerated (when frequency is increased) or decelerated (when frequency is decreased). Obviously, this method is targeted Poor, so that some tasks that do not need to be frequency-regulated are also frequency-regulated, re...
