摘要
本文介绍了一种由８０３１单片机系统构成的实时数据获取接口。该接口除具有数据获取和预处理功能外，数据传送采用以双端口ＲＡＭ为基础的内存直接映象方式。同时，还能方便地实现对ＡＤｃ变换系统的死时间或活时间的测量。
A high-performance data acquisition system applied in the multichannel analyzer is designed with single-chipmicrocomputer system. The paper proposes the principle and the method of realizing the simultaneous data acqui-sition,the data pre-processing,and the fast bidirectional data transfer by means of direct memory access hasedon dual-port RAM as well.The measurement for dead or live time of ADC system cn also be implemented effici-ently by using it.(
