Non-blocking parallel triangle rasterization unit structure

Abstract

The invention provides a non-blocking parallel triangle rasterization unit structure. The triangle rasterization unit structure consists of 7 functional pipeline stages, which are a triangle vertex receiving unit, a triangle scanning parameter establishment unit, an edge function method Tile scanning unit, a boundary Tile pixel position relation judgment unit, a boundary Tile pixel anti-aliasing unit, a Tile attribute interpolation request arbitration unit and a Tile attribute interpolation unit in sequence from front to back. The triangle rasterization unit structure has capabilities of non-blocking parallel triangle block scanning and processing; pixel Tiles covered by a triangle are classified into two types including Tiles completely in the triangle and Tiles partially in the triangle;two parallel processing channels are set; on the premise of keeping a triangle Tile output sequence, non-blocking parallel scanning of the two types of the Tiles can be realized; the resource utilization rate, the triangle processing capability and the pixel generation capability are improved; and especially for relatively large triangle primitives, the structure is more effective.

Description

technical field [0001] The invention belongs to the technical field of computer hardware and relates to a non-blocking parallel triangle rasterization unit structure. 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, th...

Problems solved by technology

[0003] At present, there is no GPU based on a unified dyeing architecture in my country, and a large number of commercial GPU chips imported from abroad are used in display control systems in various fields.

Especially in the military field, foreign imported commercial GPU chips have poor temperature and environmental adaptability, cannot guarantee that the circuit itself or supporting software has no "back door", contains a large number of redundant functional units that are not needed in the military field, and the power consumption index cannot meet the requirements. Commercial GPU chips are updated quickly, facing production stoppages and outages at any time, making it difficult to meet defects such as continuous support of weapons and equipment, and there are major hidden dangers in terms of safety, reliability, and support.

Moreover, due to political, military, economic and other reasons, foreign countries have implemented technology "blockade" and product "monopoly" on my country, making it difficult to obtain the underlying technical information of GPU chips, such as register information, detailed internal micro-architecture, core software source code, etc., resulting in GPU functions and performance cannot be fully utilized, and the portability is poor; the above problems seriously restrict the independent research and development of display systems in my country
