Hardware Design Of Video Process System Based On TMS320DM642

With the development of computer, Internet and microelectronics, the video process system was widely applied in daily life, military, industry, medical treatment and others. The video process system based on the DSP ( digital signal processor ) , as an important technique of real-time video process, has been the emphasis of research. The hardware implementation of video coder and decoder is the precondition to process and transmit the digital video, so it is important to research the video process system based on the DSP.In this paper, the development and implementation methods of the embedded video process system are researched and analyzed at first, including the system based on special image process chip, the system based on high speed DSP and the system based on personal computer. On the foundation of research and taking into account the design requirement of this system, the implementation method that the hardware designs of video system based on DSP was discussed with emphasis, and the detail design is given. At the same time, the paper introduces the program design of the process system based on TMS320DM642, including the peripheral selection, system initialization,...
