Problems solved by technology

OpenGL2.0 defines the method for calculating the texel address of texture maps, but there are many factors to consider in the calculation of texel address, including the texture coordinate wrapping mode, the filtering mode of shrinking / enlarging textures, texture border settings, etc., and the details of the algorithm defined by OpenGL2.0 Not sure, especially when the texel address is at the edge or exceeds the boundary, the effect achieved is quite different from the effect of the current commercial platform
It is very difficult to perfect this algorithm structure in the logic design of GPU chip hardware, and to verify it completely

Abstract

The invention relates to the technical field of computer hardware modeling, in particular to a TLM microstructure oriented to a GPU hardware texel valuing method. The TLM microstructure comprises a texel information acquisition module 1, a texel coordinate processing module 2, a filtering mode texel address correction module 3, a frame texel address correction module 4 and a texel valuing module 5. According to the microstructure, the function and the implementation structure of the texel address correction algorithm based on the TLM model are achieved, the function verification problem of thecorrection algorithm oriented to the GPU hardware texel address TLM microstructure is solved, and RTL design and development are effectively accelerated.

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a TLM microstructure oriented to GPU hardware texel value acquisition methods. Background technique [0002] In the design and development of a graphics processor chip (hereinafter referred to as GPU), the correctness and efficiency of algorithms are important factors that determine the function and performance of the GPU. OpenGL2.0 defines the method for calculating the texel address of texture maps, but there are many factors to consider in the calculation of texel address, including the texture coordinate wrapping mode, the filtering mode of shrinking / enlarging textures, texture border settings, etc., and the details of the algorithm defined by OpenGL2.0 It is not clear that especially when the texel address is on the edge or exceeds the boundary, the effect achieved is quite different from the effect of the current commercial platform. It is very difficult...
