基于USB总线的HDLC接口设计

USB Bus-based HDLC Interface Design

介绍了一种基于USB总线的HDLC接口的实现方法，描述了其工作原理，并给出了软硬件设计方法。设计中采用了FPGA等当今流行技术，在完全实现功能需求的同时也很好的兼顾了后期功能扩展和升级。

HDLC based on USB bus interface implementation method was introduced,describes the working principle,and gives the software and hardware design,FPGA design using today＇s popular techniques,in the full realization of functional requirements and also features a good balance between the expansion and upgrade later.
