摘　　要：数据适配器是数字通信系统的重要组成部分之一,用于数据源与数据集之间的数据交换,将数据从数据库读入数据集,然后将已更改的数据从数据集写回数据库。数据适配器重要功能之一是针对不同数据制式之间的转化。重点讨论了HDB3码与不归零码(NRZ码)之间的相互转换,并就以数据适配器为中心的数字通信系统,使用Quartus Ⅱ软件进行设计与仿真,下载到GW48-PK2型EDA实验平台进行测试与验证。Data adapter is one of the crucial part of an digital communication system, which is used to exchange data between data source and data set. Data adapter reads data from data base into data set, and then writes the renewed data back. It is widely used in the translation of two different data types. The focus of the paper is the transformation between HDB3 code and NRZ code, and the design of data communication system based on the data adapter. The design and simulation work are done with the help of Quartus II simulating software, and further test work is finished on the GW48 -PK2 EDA experiment platform.
