Parallel rasterization sequencing method of triangular primitives

Abstract

The invention relates to the technical field of computer hardware, particularly to a parallel rasterization sequencing method of triangular primitives. The method at least comprises a triangular pixeltile scanning phase, a boundary pixel tile processing phase, a complete interior pixel tile processing phase, a pixel tile attribute interpolation request arbitration phase, and a pixel tile attribute interpolation phase. Therefore, the utilization rate of the hardware resources of the rasterization unit can be increased, so that the processing throughput rate and the pixel generation capabilityof the triangular primitives are improved; and especially for the triangular primitives with the large proportion in the complete interior pixel tile and the triangular boundary pixel Tile, the performance is improved obviously.

Description

technical field [0001] The invention relates to the technical field of computer hardware, and relates to a parallel rasterization and sequencing method for triangular primitives. 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...

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
