Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0060] For ease of understanding, the terms involved in the embodiments of the present application are firstly explained below.

[0061]"Multiple" in this application refers to "two or more" or "at least two" unless otherwise specified. "A and / or B" appearing in this application includes at least three situations of "A", "B" and "A and B".

[0062] Instruction Stream: A collection of one or more computer-readable instructions. In some implementation manners, an instruction may include information such as an instruction name (or called a function name) and parameters, and the instruction name may also be regarded as a type of "parameter". In some implementations, the instruction can continue to be split into more instructions. F...

Abstract

The invention discloses an image rendering method and device, electronic equipment and the like, and can be applied to the field of terminals. The method comprises the following steps that: a centralprocessing unit (CPU) acquires an image instruction stream for rendering an image frame, and compares the image instruction stream with a previous image instruction stream; and when the same drawing instruction exists in the two image instruction streams, a graphics processing unit GPU is instructed to render the image frame based on a previously generated drawing target. That is to say, the GPU can reuse the drawing targets with the same drawing instruction in different image frames, so that the generation process of the drawing targets is reduced, and the load of the GPU is reduced.

Description

technical field [0001] The present application relates to the field of computers, and in particular to an image rendering method and device, electronic equipment, and the like. Background technique [0002] With the rapid development of terminal technology, terminals such as computers and mobile phones can realize various functions by installing different application software. When some application software in the terminal is running, it will simultaneously use a central processing unit (Central Processing Unit, CPU) and a graphics processing unit (Graphics Processing Unit, GPU) in the terminal. [0003] Among them, the GPU can realize the image rendering function under the control of the CPU. The image rendering includes performing operations such as geometric transformation, projection transformation, perspective transformation, and window clipping, as well as the process of generating images according to material and light and shadow information. Specifically, the GPU re...
