Hybrid rendering in graphics processing

Abstract

This disclosure presents techniques and structures for graphics processing. In one example, a method of graphics processing may include rendering, with a graphics processing unit (GPU), one or more portions of a frame using one or more graphics operations, and writing, with the GPU, color data directly to a color buffer in a system memory in accordance with the one or more graphics operations. The method may further include writing, with the GPU, depth data to a depth buffer in a graphics memory in accordance with the one or more graphics operations, and resolving, with the GPU, the depth buffer in the graphics memory to the system memory when the rendering of the one or more portions of the frame is complete.

Description

technical field [0001] The present invention relates to techniques for graphics processing, and more particularly, to techniques for mixed rendering modes in graphics processing. Background technique [0002] Visual content for display, such as content for graphical user interfaces and video games, may be generated by a graphics processing unit (GPU). A GPU can convert two-dimensional or three-dimensional (3D) objects into a displayable two-dimensional (2D) pixel representation. Converting information about a 3D object into a displayable bitmap is called pixel rendering and requires considerable memory and processing power. In the past, 3D graphics capabilities were only available on powerful workstations. However, 3D graphics accelerators are now commonly found in personal computers (PCs) as well as in embedded devices such as smart phones, tablet computers, portable media players, portable video game consoles, and the like. Typically, embedded devices have less computin...
