Abstract

The invention belongs to the field of computer graphics, and in particular to a graphic command pre-decoding model based on a SystemVerilog dynamic array and a task. The model comprises a preparationtask block, a command analysis task block, a drawing type command processing task block, a parameter configuration type command processing task block, a display list command processing task block, a display list writing task block and a display list reading task block. In the working process of the model, operation data and output results are dynamic arrays of SystemVerilog, read and write tasks of a preparation task and a display list further achieve interaction with files, and data comparison and check in the verification process are facilitated. The processing process does not contain a time sequence, processing tasks of various commands store results into corresponding dynamic arrays, the process is clear, maintenance is convenient, and the simulation speed is greatly increased.

Description

technical field [0001] The invention belongs to the field of computer graphics, in particular to a graphics command pre-decoding model based on SystemVerilog dynamic arrays and tasks. Background technique [0002] In the field of computer graphics, there are many kinds of OpenGL graphics commands. OpenGL programs written by software personnel need to be preprocessed according to the defined command format before entering the processing flow of the GPU. The pre-decoding unit performs preprocessing operations. key circuits. Since the pre-decoding unit includes at least two data sources and multiple processing delivery channels, when it is verified, it first encounters the problem of verification correctness, which requires a comparison of the design output model, but there is no specific construction scheme for this model in the prior art. Contents of the invention [0003] Aiming at the problems existing in the background technology, the present invention now proposes a g...
