Caijuan Shi, Guoqiang Hou, Jian Liu · 2010
This paper introduces the composition and operating principle of the image test signal generator about HDTV based on CPLD, it explains the logic function design in CPLD and the hardware configuration of this system in detail. The signals produced by this generator accord with the parameter standard of video signal interface about our national High Definition Television. Furthermore, programming with hardware description language VHDL makes it easy to expand software functions.
