摘　　要：图象存贮体是图象处理系统中必不可少的核心部件之一。它实现图象数据的接收、发送和存贮等功能,同时作为高速设备与低速设备之间的缓冲环节,以满足对图象处理系统多方面的要求。本文着重介绍实时图象处理系统中图象存贮体的设计及其工作原理,同时提供了它与计算机之间的DMA数据交换方式。Image memory is a dispensable part for real time image processing. It stores,transmits image data, and can be used also as a buffer unit between high-low speed system. In this paper, the principles and constructions of the image memory used in real time image processing system are presented. The DMA (Direct Memory Access ) mode used to exchange its data with computer is also discussed in detail.
