Implementation of HDLC protocol based on FPGA in communication systems
HDLC协议在FPGA通信系统中的实现

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.
