本文叙述用外部静态存贮器作为微机的扩展内存,存入实时遥测信息,供微机进行处理。基本思想是开辟两个静态存贮区,这两个存贮区的读写由遥测帧信号控制,一帧一交替,也就是一帧在一个存贮区存入由遥测接收设备来的实时遥测信息,而另一存贮区则作为微机内存,由微机控制处理已存入的遥测信息,下一帧进行一次交换,即已处理过的存贮区开始存入新的遥测信息,而已存入遥测信息的存贮区作为微机内存,再由微机控制,进行处理,遥测数据的加工处理可用程序中断方式(Z中断)进行。
This article describes the use of external static memory as an extension of the microcomputer memory, stored in real-time telemetry information for the computer to process. The basic idea is to open up two static storage area, the two storage area read and write by the telemetry frame signal control, one by one alternating, that is, a frame stored in a storage area by telemetry receiving equipment to real-time telemetry Information, while the other storage area is used as a microcomputer memory, microcomputer control processing has been stored telemetry information, the next frame to be exchanged, that is, the storage area has been processed into a new telemetry information, and has deposited Telemetry information storage area as a computer memory, and then controlled by the computer, processing, telemetry data processing can be interrupted by the program (Z interrupt).
