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 storage is one of the essential components of an image processing system. It realizes the functions of image data receiving, sending and storage, at the same time, it serves as a buffer between high-speed equipment and low-speed equipment to meet various requirements of image processing system. This article focuses on the design and working principle of the image memory in the real-time image processing system and provides the DMA data exchange mode between it and the computer.
