该工程是基于verilog hdl 语言编写的帧传输协议HDLC帧的发送端代码，会用QUATUSII的人都应该知道如何使用，希望能给你带来帮助-The project is based on the language verilog hdl frame transmission protocol HDLC frame of this generation- Codes will be used QUATUSII people should know how to use, in the hope of giving you helpful

这是很全的标准库啊，不是1164.vhd，都是一些加，乘，除，平方等操作的包来的．-This is the standard for the whole ah, not 1164.vhd are some increases, multiplication, addition, operational square packages to come.

本程序给出了在FPGA板上实现LCD显示的方法。支持的FPGA有APARTAN 3、SPARTAN 3E、VIRTEX 3等

交通灯控制器的VHDL设计,能控制十字路口的红绿灯转换,通过目标芯片EPF10KLC84-4验证-Traffic lights controller VHDL design, can be controlled by traffic lights at the crossroads of the conversion, through the target chips EPF10KLC84-4 verification
