Structure of image processing unit system of graph processor

Abstract

The invention relates to a structure of an image processing unit system of a graph processor, and belongs to the field of graph processor design. The structure is composed of a front image pipeline segment unit, an image processing subclass unit, a rear image pipeline segment unit, an arbitration unit, a format conversion B unit, a compression and decompression unit and a decoding control unit. Main data including pixel, texture and bitmap can be loaded and obtained, auxiliary data including a color table and the convolution kernel is loaded and obtained, and in the data loading and obtainingprocess, functions including storage, pixel transmission, pixel mapping, pixel zooming, color table, convolution, color table transformation, column chart statistics and minimum and maximum calculation operations prescribed by the OpenGL standard are supported.

Description

technical field [0001] The invention belongs to the design field of graphic processors, and relates to a system structure of an image processing unit of a graphic processor. Background technique [0002] Graphics processing unit (GPU) is a key component for graphics drawing, image and video processing and display, and is commonly found in various systems that need to accelerate window systems, graphical interfaces, game scenes, image applications, and video playback. The image processing unit is an important part of the GPU responsible for loading and reading pixel, texture and bitmap data, and performing color transformation and processing during the loading and reading process. It is responsible for providing support for the GPU's image pipeline and image processing subset functions and achieve. [0003] At present, my country's GPU research and development capabilities are weak, and a large number of imported commercial chips are used for graphics acceleration in various...

Problems solved by technology

Due to reasons such as national security and commercial interests, the underlying information of commercial GPUs (such as internal micro-architecture, core design, etc.) has never been made public, resulting in the inability to fully utilize the functions and performance of commercial GPUs during use, and poor portability; in addition , in the military field, foreign commercial GPUs have hidden dangers in terms of safety, reliability, and support, and it is difficult to meet the independent support needs of military applications.

[0004] The above problems have seriously restricted the independent research and development of various graphics acceleration systems in my country. The development of GPU chips with independent intellectual property rights is imminent, and the image processing unit is used as the GPU to load and read pixels, textures, etc., and simultaneously perform transformation and processing. There is no public report on its realization structure, and it is urgent to study and make breakthroughs in its design technology
