Two-dimensional-graphics acceleration method based on GCN (Graphics Core Next)-architecture display card

Abstract

The invention discloses a two-dimensional-graphics acceleration method based on a GCN (Graphics Core Next)-architecture display card. On the basis of the characteristics of a general graphics acceleration framework EXA under an X window system and the GCN-architecture display card, the two-dimensional-graphics acceleration method of the GCN-architecture display card is realized through realizing main acceleration operations under the EXA acceleration framework. The method has the advantages of: quickly establishing a rendering link, carrying out state programming and shader programming on theGCN-architecture display card, utilizing vertex resources, texture resources and constant resources, and thus completing the two-dimensional acceleration method under the EXA acceleration framework; avoiding the disadvantages that an acceleration method in a Glamor acceleration manner requires tedious processes of firstly calling EGL to initialize a graphics rendering environment, and then callingan API interface in OpenGL to switch a context process into three-dimensional-graphics rendering, realization of an entire acceleration interface is also greatly improved on aspects of time complexity, stability and memory consumption, and two-dimensional-graphics acceleration performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a two-dimensional graphics acceleration method based on a GCN architecture graphics card. Background technique [0002] GCN (Graphics Core Next) is the code name of a series of microarchitecture and instruction set developed by AMD. The first product of the GCN architecture was launched in 2011, and the AMD GCN architecture series has undergone five iterations so far. Before R600 graphics cards, AMD / ATI graphics cards have a dedicated area copy acceleration hardware unit, and the driver can directly control this hardware unit to perform corresponding two-dimensional acceleration operations. The 2D acceleration hardware unit is removed from the R600 architecture and later graphics cards, and all 2D acceleration operations are implemented by the 3D unit. Compared with the previous graphics card, the GCN architecture graphics card has high parallel processing ...
