Research on key problems in development of video/image microsystem

According to the problems easily appeared in widely used TMS320DM642 processor during the video/image sys tem development,these problems are summarized and analyzed from the point of engineering practice.The principle of DM642 video/image microsystem is introduced,then the problems that may come out during the circuit design,p software rogramming and FLASH burn are deeply analyzed,and also the corresponding solutions are proposed.The practice development of the image system was done based on TMS320DM642 processor.These results from the summary and analysis can effectively provide assis tance for the development of DM642 video/image system.
