Embedded image system based on DM642

Based on TMS320DM642, integrated with video decoder TVP5150 and CF card, fabricate the high performance embedded image system. The Developed system has a great many of advanced features, such as multichannel image acquisition in high speed mode、flexibility of image processing arithmetic、mass memory for data storage etc., including characteristics of low power and all-purpose application. The design of system’s architecture and the functions of each module are expounded, the hardware schematics of system are given, the problems coming up in practice are discussed and solutions are offered. The outlook of the application of the system designed in this paper is capacious, and the technique can be generalized to relative domain.
