HDLC控制协议的FPGA设计与实现

Design and implementation of a HDLC protocol controller based on the Field Programmable Gate Arrays

设计了一种基于FPGA的HDLC协议控制系统,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。重点对协议的CRC校验及“0”比特插入模块进行了介绍,给出了相应的VHDL代码及功能仿真波形图。

A HDLC protocol controller is designed. Without unwanted peripheral circuit, based on the Field Pro-grammable Gate Arrays and taking advantage of its high scale integration, the controller works easy and achieves a satisfactory performance.The CRC verification and '0' insert module of the HDLC protocal are intro-duced,and the VHDL program and its function emulate waveform are also given.
