Abstract

The invention provides a GPU (Graphics Processing Unit) dynamic frequency modulation method, device and system, which are used for solving the technical problem that in the prior art, a proper processor operation frequency cannot be found to reduce the power consumption of a processor. The method comprises the following steps: obtaining the graphic rendering amount of each frame of image in real time; performing classification processing on the graphic rendering amount to obtain a category corresponding to the graphic rendering amount; a sample database is called, the target frequency corresponding to the category is determined, and the sample database comprises the corresponding relation between multiple categories and frequency parameter sets; and adjusting the working frequency of an image processor GPU of the VR equipment to the target frequency.

Description

technical field [0001] The present invention relates to the technical field of 3D graphics rendering and image processor (Graphics Processing Unit, GPU) dynamic frequency modulation, in particular to a method, device and system for GPU dynamic frequency modulation. Background technique [0002] In Virtual Reality (VR) equipment, due to the need for real-time 3D graphics rendering, there are high requirements for GPU frequency modulation and system power consumption, and most of the existing dynamic frequency modulation schemes use dynamic voltage and frequency adjustment (Dynamic Voltage and frequency scaling (DVFS) technology, DVFS is a commonly used power management technology in computer architecture, which refers to dynamically adjusting the operating frequency and voltage of the processor according to the needs of the computing power of the processor during the running of the program, so that The power provided can not only meet the requirements of the normal operation ...
