A Pipeline Texture Mapping Unit System

Abstract

The invention relates to a stream line texture mapping unit system structure. A texture mapping unit comprises a level computing unit, a task allocation unit, a four-path texture address computing unit, a first data assembly and task allocation register, an L1 texture cache, a second data assembly and task allocation register, a four-path texture data extraction and normalization unit, a third data assembly and task allocation register, a four-path texture comparator, a fourth data assembly and task allocation register, a four-path filtering unit and an output data assembly unit, which are connected in sequence. The stream line texture mapping unit system structure provided by the invention provides reference and guide functions for a GPU system for improving the texture mapping performance in a hardware acceleration mode.

Description

technical field [0001] The invention belongs to the field of graphics processor design, and relates to a system structure of a pipeline texture mapping unit. 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 graphics processing capability of GPU has been continuously improved with the widespread application of texture mapping technology. The high-speed pipeline, parallel features and flexible programmability of GPU provide a good operating platform for graphics processing and general parallel computing. [0003] At present, my country's GPU research and development capabilities are weak,...

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 graphics processor chip with independent intellectual property rights, and the texture mapping unit with high performance and pipeline structure dedicated hardware structure is the key and core of the unified dyeing graphics processor. It is urgent to conduct research and breakthroughs in its design technology
