【摘要】 在WTB底层协议的研究中,其基本帧格式与ISO3309的HDLC要求一致,故设计了一种基于FPGA的HDLC编解码器。重点介绍了协议和实现方法,给出了相应的Verilog代码,通过硬件下载与标准的WTB网卡通信,实现相应解析,达到ISO3309的标准要求.更多还原

【Abstract】 In the research of the WTB(wire train bus) protocol,its frame structure accords to the ISO03309 HDLC,so a HDLC encoder and decoder based on FPGA is designed.The WTB protocol and the method of its realization are introduced,and the Verilog HDL code is also given.In the end,a software simulation is done for the design.And the whole project is downloaded in the FPGA.The module designed can communicate with the stand WTB network interface card,and achieve the requirement of ISO3309.更多还原
