Abstract

The embodiment of the invention discloses a method and device for image rendering, wherein the method comprises that a GPU (Graphic Processing Unit) receives an instruction for the image rendering sent by a CPU (Central Processing Unit); the instruction contains an identifier of a to-be-rendered image; the GPU reads a bitmap image corresponding to the identifier in memory space which can be accessed by application programs and the GPU; and the GPU renders the bitmap image. By implementing the embodiment of the invention, the memory space can be saved; the problem about frequent process standstill caused by frequent memory distribution can be avoided; and the image rendering efficiency can be increased.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image rendering method and device. Background technique [0002] At present, the interface of the software application of the Android system can be rendered by CPU or GPU. The conventional rendering operation is to directly present the scene into a piece of memory. After the scene is loaded into the video memory through a drawing function, it is then sent to the display for display. In order to achieve some special effects, such as common environment mapping, it is necessary to render to textures and perform texture rendering operations. Rendering operations usually rely on two core components: a central processing unit (Central Processing Unit, referred to as "CPU") and a graphics processing unit (Graphic Processing Unit, referred to as "GPU"). The CPU is responsible for including measurement (Measure), layout (Layout), recording (Record), execution (Execute...
