摘要
Abstract
A system for computer video interface automatic detection was proposed based on FPGA NIOS II soft core,from the application point of view,when computers out of the factory.Computer plays a special video,and transmits the image to the detection equipment by video interface.Detection equipment converts HDMI, DP video signal into VGA RGB signal format through the video conversion chip controlled by NIOS II soft core.Detection equipment detects line signal,field Signal, and then puts the values of pixel RGB in the SRAM.Computer reads data from detection equipment through the high-speed transmission interface.It is proved by experiments that the video interface de-tection method can save labor cost and has a high detection efficiency.The detection error rate is less than 1% and equipment can detect interface which outputs 4K video 30 frames per second.关键词
