OpenGL (open graphic library) API (application program interface)-oriented graphic processor

Abstract

The invention relates to an OpenGL (open graphic library) API (application program interface)-oriented graphic processor, and belongs to a multifunctional general small-sized GPU (graphic processing unit) chip. A hardware 3D (three-dimensional) acceleration engine is integrated at the inside, the compatibility with an OpenGL 3D graphic processing API is realized, and the acceleration processing capability for building 3D graphics is provided. A 3D graphic acceleration processing-oriented storage sub system is realized on the chip, and comprises a pixel cache, a storage control and management unit and a high-speed two-channel DDR2 controller. In addition, the GPU is integrated with a display control module, and comprises a VIP (video input module) for providing a video source to realize a superposition function, and two paths of independent display controllers for providing digital display output interfaces. An I<2>C bus interface, a GPIO (general purpose input output) unit and a bus interface module conforming to PCI2.2 standards are also integrated in the GPU, and the graphic acceleration processing function can be provided for a computer system providing a PCI (peripheral component interconnect) host interface.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to an OpenGL API-oriented graphics processor. Background technique [0002] With the continuous increase of graphics applications, the early solution of graphics rendering by CPU alone has been difficult to meet the graphics processing needs of performance and technology growth, and the graphics processing unit (Graphic Processing Unit, GPU) came into being. Since the release of the first GPU product by Nvidia in 1999, the development of GPU technology has mainly gone through the fixed-function pipeline stage, the stage of separating the dyer architecture, and the stage of unified dyer architecture. Rendering gradually extends to the field of general computing. The high-speed, parallel features and flexible programmability of the GPU pipeline provide a good operating platform for graphics processing and general parallel computing. [0003] At present, my country's GPU re...

Problems solved by technology

Especially in the field of military use, foreign imported commercial GPU chips have hidden dangers in safety, reliability, security, etc., and cannot meet the needs of the military environment; "Blocking" and product "monopoly" make it difficult to obtain the underlying technical information of the GPU chip, such as register information, detailed internal micro-architecture, core software source code, etc., resulting in the inability of GPU functions and performance to be fully utilized, and poor portability; the above problems are serious Restricting the independent research and development of display systems in my country, it is imminent to break through the key technologies of graphics processors and develop graphics processor chips
