摘要: 设计了一种基于高级数据链路(HDLC)协议的数据通信系统,并将HDLC协议在现场可编程门阵列(FPGA)中实现。该系统可有效利用FPGA片内硬件资源,无需外围电路,高度集成且操作简单。着重介绍了系统中最重要的协议发送、接收模块以及”0”比特的插入删除模块的实现方法。

Abstract: A data communication system based on High-level Data Link Control (HDLC) protocol was designed, and then HDLC protocol in Field Programmable Gate Array (FPGA) was implemented. The system can take advantage of FPGA hardware effectively. It has some outstanding advantages, such as high scale integration, no need of peripheral circuit and being easy to use. This paper emphatically described the implementation methods of transmitting protocol and receiving protocol and the method for "0" bit insertion and deletion.

Key words: data communication, High-level Data Link Control (HDLC) protocol, Field Programmable Gate Array (FPGA)
