Description

Technical field [0001] The present invention relates to the technical field of computer hardware modeling, in particular to a TLM microstructure for GPU hardware line primitive rasterization scanning algorithm. Background technique [0002] In the design and development of graphics processor chips (hereinafter referred to as GPU), the correctness and efficiency of algorithms are important factors that determine GPU functions and performance. The rasterization of primitives in GPU is in the window coordinate system, a single point occupies a pixel position, and a straight line also occupies a certain line width. But in a coordinate system in the mathematical sense, a point does not occupy a position, and a straight line has no width. When calculating the coordinate position of the scanning line primitives, the line length, line width, and slope need to be corrected by parameters. However, it is long and difficult to debug the algorithm details in the hardware logic stage of the ...
