一、引言我们为PDP-11/23微计算机编制了多种数据采集程序,力图充分利用机器的资源,使其胜任各种不同要求的数据采集.目前,这些程序已经通过了运行,并已投入实际使用. 本文首先介绍了PDP-11/23微计算机及其A/D转换子系统,然后针对各种不同要求的数据采集,讨论了几种程序设计方案,同时还根据对机器性能的分析和实验的结果,得到了数据采集的两项重要指标——采集速率和数据量的上限.
I. INTRODUCTION We have developed a variety of data collection procedures for the PDP-11/23 microcomputer in an effort to make full use of the machine’s resources to make it suitable for a wide range of data acquisition needs. Currently, these procedures have been put into operation and have been put into operation Actual use.This paper first introduces the PDP-11/23 microcomputer and its A / D conversion subsystem, and then for a variety of different requirements of data acquisition, discusses several program design programs, but also based on the analysis of machine performance and The experimental results obtained two important data acquisition indicators - the collection rate and the upper limit of the amount of data.
