Graphic command pre-decoding method based on SystemVerilog

Abstract

The invention belongs to the field of computer graphics, and particularly relates to a graphic command data generation method based on a Verilog task, which comprises the following steps of: firstly,generating a packet header of a command according to the classification and format definition of an OpenGL graphic command and the number of load data; configuring load data for the command packet header, and dividing the load data into two different configuration modes when the load data is configured, one configuration mode being data generation with fixed word length; and the other mode is datageneration with configurable word length; performing command data splicing on the command packet header configured with the load data in the previous step, storing the data conforming to the width format of the command FIFO into the command FIFO, and writing the command data into the command FIFO when detecting that the command end mark is valid; according to the method, the OpenGL graphic commands can be combined and matched, the graphic commands with any length and random load content can be sent out according to the requirements of a verification scene, the graphic commands with the load content being a specific value can also be sent out, and high readability and maintainability are achieved.

Description

technical field [0001] The invention belongs to the field of computer graphics, in particular to a method for generating graphic command data based on Verilog tasks. Background technique [0002] In the field of computer graphics, in order to verify various application scenarios, it is usually necessary to construct a large number of OpenGL graphics commands. These graphics commands not only require a variety of combinations, but also must be easy to read and maintain; currently there is no reasonable and efficient technical means The method to complete the generation of graphics command data. Contents of the invention [0003] The purpose of the present invention is: [0004] In order to solve the problem that there is no reasonable and efficient technical means in the prior art to complete the method of generating graphic command data, the present invention proposes a method for generating graphic command data for verification which is beneficial for writing test vector...
