To solve the problem caused by large amount of image data and the requirement of real-time in the video image processing system, the paper design a video image processing system based on digital signal processors TMS320C6713, using the EDMA controller to realize high speed data transmission. The method of data transfers by EDMA and the software design flow are described respectively, adopting the Ping-Pong buffer technology to balance rhythm between the data transmission and CPU data processing, so the real-time requirement of the video image processing system could be satisfied.
