Abstract

The application discloses a method and a device for adjusting the operating frequency of a central processing unit core. A specific implementation of the method includes: performing the operation of collecting the operating frequency of the core of the central processing unit every interval of a first preset time period; The data of the event of the core operating frequency of the device; the data of the operating frequency and the event affecting the operating frequency of the central processing unit core are calculated and processed; the results obtained by the calculation process are imported into the preset central processing unit as input parameters A kernel utilization prediction model is used to obtain the predicted utilization of the central processing unit core; based on the predicted utilization, the operating frequency of the central processing unit core is adjusted. This implementation manner satisfies the requirements of CPU processing tasks and effectively controls the operating frequency of the CPU core, thereby reducing the power consumption of the CPU and realizing energy saving.

Description

technical field [0001] The present application relates to the field of computer control, in particular to the field of processor control, in particular to a method and device for adjusting the operating frequency of a central processing unit core. Background technique [0002] With the popularity and rapid development of computers and the Internet, computers and their applications have become ubiquitous in people's daily lives. However, while computers are enriching people's daily life, their power consumption is getting higher and higher. High power consumption will reduce the running time of the computer system, and more importantly, it will increase the temperature of the computer equipment when it is used, which in turn will shorten the life of the equipment. reduction. [0003] With the continuous improvement of hardware technology, the power consumption of the central processing unit (Central Processing Unit, CPU) accounts for a higher and higher proportion of the pow...
