Single-instruction multi-thread staining processing unit structure for uniform staining graphic processing unit

Abstract

The invention belongs to the field of graphic processing unit design, and relates to a single-instruction multi-thread staining processing unit for a uniform staining graphic processing unit. The processing unit comprises four SC (Staining Core) units (1) used for executing a conventional operation, an SFU (Special Function Unit) (2) used for executing a special performance function, a BRU (Branching Unit) (3) used for carrying out program branching, five sets of RF (Register File) units (4) used for data storage and five sets of LSRAM (Local Storage Random-Access Memory) units (5) used for data storage, wherein one set of RF unit (4) corresponds to one SFU (2), and the rest four sets of RF units (4) correspond to the four SC units (1) one by one; and one set of LSRAM unit (5) corresponds to one SFU (2), and the rest four sets of LSRAM units(5) correspond to the four SC units (1) one by one.

Description

technical field [0001] The invention belongs to the design field of graphic processors, and relates to a single-instruction multi-thread dyeing unit of a graphics processor with a unified dyeing architecture. Background technique [0002] Graphics processor (Graphic Process Unit, GPU) is an important part of modern computer hardware, and it is a key component for graphics drawing, processing and display. system. The GPU is responsible for generating 2D and 3D graphics, images, and videos to support visual computing such as window-based operating systems, graphical user interfaces, video games, visual image applications, and video playback. The development of GPU technology has mainly gone through the stages of fixed-function pipeline, separated shader architecture, and unified shader architecture. Its graphics processing capability has been continuously improved, and its application field has gradually expanded from the initial graphics drawing to the general computing fiel...

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 development and independent development of my country's display system, it is imminent to develop a unified dyeing graphics processor chip with independent intellectual property rights, and the single-instruction multi-threaded dyeing unit is used as a dyeing unit cluster and a unified dyeing array unit in the unified dyeing graphics processor. The key and core of its design technology research and breakthrough has become urgent
