道路检测

fifo程序代码，程序编写，测试仿真图形，方便，比较实用(fifo code, programming, testing, simulation graphics, convenient and more practical)

数字频率计，测量范围0-1GHZ,测周测频自动转换，精度极高，花了很长时间，不过还是有一点点小问题，有待改进.(Digital frequency meter, range 0-1GHZ, automatic conversion measured weekly frequency measurement, high precision, took a long time, but still a little small problems to be improved.)

说明：  使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)

许多非常有用的 Verilog 实例: ADC, FIFO, ADDER, MULTIPLIER 等(many very useful Verilog examples : ADC, FIFO, ADDER, MULTIPLIER etc.)

它支持ahb接口它是一个内存模型，当传输完成时给出正常响应，当发现地址超出范围时给出错误响应

VHDL黄金参考手册，能让你更好的学习了解VHDL语言(VHDL gold reference manual, can make you a better learn VHDL language)

用Verilog HDL语言进行HDB3编码，并通过Quartus Ⅱ仿真验证(With the Verilog HDL language HDB3 coding, and simulation by Quartus Ⅱ)

自己写的布斯4算法的华莱士树无符号数乘法器，3-2压缩，亲测可用(Wallace wrote the number 4 Booth algorithm unsigned multiplier, 3-2 compression, pro-test available)

几大代工厂的flash verilog源代码(flash verilog code)

fpga与pc的串口通信，使用fifo作为数据缓存。数据从串口读入，存入读取缓存rdfifo里面，然后由控制模块控制，将数据存入写出缓存wrfifo中，串口TX口向WRFIFO发出读取数据的请求，读取数据。
