高速数据采集系统中精确时标的CPLD实现方法

A method of realizing precise time label in high-speed data acquisition system

介绍一种利用复杂可编程逻辑器件给高速数据采集系统中的采集数据贴上精确时间标签的方法,并利用MAXPLUSⅡ开发环境验证设计方案的正确性。此设计方案已经成功地应用到自行设计的高速数据采集卡中。

This paper introduces a new method, using complex programmable logic device to attach a precise time label to the data gathered in high-speed data acquisition system. It has used MAX PLUS II to simulate the function, and the results proved to be accurate. The system has been applied in high-speed acquisition sample board, which has been designed successfully.
