With the micro-electronics technology , computer technology , network technology , as well as the rapid development of artificial intelligence , digital video systems in many areas of life , production , military a wide range of applications , especially video surveillance system because of its broad application prospects has become a research focus. Traditional video systems are usually based on the PC system , PC, large volume , high- cost , long-distance should not be placed on the site and power limited shortcomings by small size , low power consumption , low - cost embedded systems video surveillance trends. Meanwhile, with the processing power of the DSP chip continuously improve the DSP-based embedded real-time video processing system has become the focus of the study of video applications . This paper studies based on TI's dual-core video processing chip a TMS320DM6446 the embedded video surveillance system , not only can give full play to the DSP core multi-processing unit multi- stage pipeline advantage of high-speed processing of image data , the effective use of the ARM core the excellent peripheral control ability to complete the network transmission and complex peripheral control . At the same time , the system is still small size , low cost , easy installation . Thesis completed work includes : TMS320DM6446 DSP - based video hardware circuit design , to containing video input and output modules , network communication modules , power modules , memory modules, etc. ; system hardware, high-speed circuit design and simulation, signal integrity analysis , electromagnetic compatibility analysis ; 12 - layer printed circuit board layout , wiring and digital simulation ; embedded operating system software configuration, including the Bootloader programming .
