Abstract

Time is the best important resource in real-time video image processing system. Only few structure or algorithm can be used in real-time video image processing system because of time limitation. Establish a high speed data-access is a way to this problem. It transfer the video signal between output ports and kernel processor as less time delay. The mode, look-up-table, other analysis, adjustment or calculation rule will be applied first by medium or low data-access. We can choose different data-access according to data relation level. Data which has closer correlation will be treated through low-speed-access, which has loser correlation will be treated through medium-speed-access. Theory analysis and experiment showed that it is a high effective structure for real-time video image processing. The feature of video image and real-time processing system is presented in this paper. The basic theory of data-access is introduced also. The status and relation of high, medium, low data-access is discussed and the rules of data distribution in different access is analyzed. Some examples with datas-accesses are given in the paper (TV tracking and measuring, laser signal alarming system).
