| Abstract: | The embedded system uses TMS320DM642 as the core processor, and the system is composed of video A/D＆D/A modules and video processing modules. The system realizes the entire function including analog video signal input, video capture processing, video processing and video reference information output. The system is designed by the idea of modulation driver is proved to be simplified using IOM driver module to design It shortens development cycle and system video driver, maximize code reuse as development of video well as universality. |
