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

Abstract

The present invention relates to the technical field of computer hardware modeling, and provides a UML-oriented GPU fragment rendering task scheduling method, comprising: step 1: initialization unit, denoted as Pixel_Assemble_Initialize; step 2: image data assembly unit, denoted as Pixel_Ipu_Assemble; 3: Geometry engine data assembly unit, denoted as Pixel_Geu_Assemble; Step 4: Debug information processing unit, denoted as Pixel_Debug_Assemble. The invention models the GPU fragment shading task scheduling unit through UML language and transaction level modeling method, specifically including the structure view of the GPU fragment shading task scheduling unit and the behavior diagram inside the unit. It can help system developers better understand the system architecture and functions, establish a more reliable and complete system model, and verify the feasibility of the hardware structure more efficiently.

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a UML-based method for scheduling GPU fragment coloring tasks. Background technique [0002] UML (United Modeling Language), also known as Unified Modeling Language, is a graphical language that supports modeling and software system development. It provides modeling and visualization support for software development. UML can help designers shorten design time and reduce improvement costs. Optimize hardware and software partitioning. [0003] The high-speed, parallel features and flexible programmability of the GPU pipeline provide a good operating platform for graphics processing and general parallel computing. At present, my country's GPU research and development capabilities are weak, and a large number of commercial GPU chips imported from abroad are used in display control systems in various fields. Especially in the field of military use, foreign importe...
