Test system for testing graphic processing module

Abstract

The invention discloses a test system for testing a graphic processing module. The test system comprises a computer and a signal adapter box, wherein the computer internally comprises test software, an Ethernet communication module and a video acquisition card; the signal adapter box internally comprises a signal conversion module, a main control module and the tested graphic processing module; the test software is used for generating various plotting instructions and controlling the Ethernet communication module to transmit the plotting instructions to the signal adapter box; through DVI (Digital Video Interactive) images read by the video acquisition card, an evaluation report is obtained for the tested graphic processing module; the main control module is used for analyzing the received plotting instructions and inputting the plotting instructions to the tested graphic processing module; the tested graphic processing module is used for making a response to the plotting instructions and generating corresponding VGA (Video Graphics Array) images; and the signal adapter box is used for converting the VGA images output by the tested graphic processing module into DVI images and outputting the DVI images to the computer. The test system realizes the testing of the plotting capability and a video transmission function of the tested graphic processing module.

Description

technical field [0001] The invention relates to a test system for testing a graphics processing module, in particular, a multifunctional testing system for a graphics processing module based on LabVIEW. Background technique [0002] Recently, with the rapid development of the aviation industry, especially in the past, mechanical instruments tend to be electronic and virtualized, and the integration of pilot operation interface functions on the display screen is relatively high, which puts forward higher requirements for the graphics processing module in the display and control equipment. At present, traditional test methods are used in China to test graphics processing module single boards, specifically, use independent external simulation equipment and develop special test programs to test interfaces and power consumption separately. This traditional method has the following disadvantages: for different The interface needs to provide dedicated test equipment and develop a d...

Problems solved by technology

At present, traditional test methods are used in China to test graphics processing module single boards, specifically, use independent external simulation equipment and develop special test programs to test interfaces and power consumption separately. This traditional method has the following disadvantages: for different The interface needs to provide dedicated test equipment and develop a dedicated test program. The test range is narrow and the process is single, and the manual judgment has a greater impact; the lack of functional testing of the graphics processing module increases the difficulty of system joint test fault isolation; and poor compatibility , increase repeated development work; in addition, the intermediate parameters cannot be tested, and the test is not detailed enough
