摘要

<正> IRSA-2型遥感图像分析处理系统以ECLIPSE S 140计算机为主机

主要用户设备为COMTAL VISION ONE/20图像显示器。要发展一个完整的计算机图像分析处理系统

必须在完成计算机和图像显示设备的硬件连接、并能在机器语言下正确运行后

将用户设备纳入计算机的操作系统。S140计算机的AOS操作系统本身具有复杂和严密的结构

将用户设备

特别是同时使用程序输入出及高速直接数据通道的图像显示器纳入

Abstract

In the article

the software interface of the IRSA-2 Digital Image Processing Subsystem with the AOS operating system of the Data General Eclipse S140 computer is descri-ted. Few alternatives have been compared and tested

and the Inter-Process Communication bechnique has been used

with this technique

the user device is connected into the AOS operating system which founded the base for development of the IRSA-2 Digital Image Processing S stem. In IRSA-2 system

the image disppay device can be shared by multiu-sers by means of utilization of virtual image display technique. Therefore

the computer resources are used efficiently.
