Triangular rasterized scanning structure based on TLM

Abstract

The invention relates to a triangular rasterized scanning structure based on TLM (Transaction Level Models), including an initialization unit which is connected with a data acquisition unit through atransaction level port and is used for receiving triangular data information and obtaining the X-axis starting coordinates and the Y-axis detection range according to the triangular data information,a Y-axis stepping unit which is connected with the initialization unit through a transaction level port and is used for carrying out enabling identification on the X axis and controlling the steppingof detection elements along a first direction according to the Y-axis detection range, and a number of X-axis scanning units which are used for controlling the scanning of the detection elements alongthe X axis according to the enabling identification of the X axis and the X-axis starting coordinates. The triangular rasterized scanning structure integrates the initialization unit, the Y-axis stepping unit and the X-axis scanning units, and the initialization unit, the Y-axis stepping unit and the X-axis scanning units are connected in turn through the transaction level ports, so that X-axis scanning and the Y-axis stepping can be executed in parallel, the complexity of triangular rasterization is reduced, and the scanning performance and speed of the triangular rasterized scanning structure are improved.

Description

technical field [0001] The invention relates to the technical field of computer graphics scanning, in particular to a TLM-based triangular rasterized scanning structure. Background technique [0002] With the continuous increase of graphics applications, the early graphics rendering solutions relying solely on CPU (Central Processing Unit, Central Processing Unit) have been difficult to meet the graphics processing needs of technological growth, so Graphic Processing Unit (GPU) came into being pregnancy. 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 shader architecture, and the stage of unified shader architecture. Rendering gradually extends to the field of general computing. GPU has the characteristics of high-speed pipeline, parallelism and flexible programmability, and provides a good operating platform for graphics processing and gen...

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

[0004] At present, the structure used for GPU triangle rasterization scanning is realized through the Zigzag algorithm, but the structure used for GPU triangle rasterization scanning implemented by the Zigzag algorithm, the Y-axis step is too dependent on the end position of the X-axis bidirectional scanning, Increased the complexity of triangle rasterization, affecting the scanning performance and speed of the triangle rasterization scanning structure
