使用VHDL编写的分频程序,能进行任意次的偶数分频,程序简单易懂,供 初学者参考...

有用的数字钟设计文档，有秒表、闹钟等模块，希望对大家有用！(JUST LEARN FROM IT!!ENJOY!)

FIR滤波器的VHDL语言实现(The implement of FIR Filter based on VHDL)

清华大学电子课程设计：Verilog，QuartusII可正确运行，可下载到FPGA上，完成远程通信的整体任务，PC发数据，键盘输入运算符与运算数计算将结果显示在数码管上并返回给PC机，需异步串口调试软件(Verilog, QuartusII run correctly, can be downloaded to the FPGA, to complete the overall task of remote communication, PC send data, keyboard operators and operands calculation displays the results in digital tube and returned to the PC, to be asynchronous serial debugging software)

32位加法器作为VHDL编写的第一个代码；

FFT程序，此程序虽然耗逻辑资源很大，但是在接受数据后的第7个时钟沿就可以输出FFT变换后的数据，对要求时延较低的系统可以考虑-FFT procedure, this procedure should not consume a lot of logic resources, but the data in the first seven clock can be output along the FFT transformed data, the requirements of time-delay system can be considered lower

说明：  用于FPGA的I2S接收模块，仅供学习和参考(audio-i2s receive.use fpga.)

FPGA核心代码，可在工程中直接使用。-FPGA core code, can be directly used in engineering.

内容有VHDL语法总结及相应的实例应用，每个程序我都亲自试过，特别适合初学VHDL的同学们。常用的程序有 设计一个M序列发生器，M序列为“11110101”、 设计一个彩灯控制器，彩灯共有16个，每次顺序点亮相邻的四个彩灯，如此循环执行，循环的方向可以控制。设计一个跑马灯控制器。一共有8个彩灯，编号为LED0~LED7，点亮方式为：先从左往右顺序点亮，然后从右往左，如此循环往复等等。这些都是我在考试前熬夜总结的，很有用。如果配合开发板用的话，那就更好了 ( VHDL syntax summary content and the appropriate application instance, every program I have personally tried, especially for students of beginner VHDL. Common program has designed a sequence generator M, the M series is 11110101 , a lantern controller design, a total of 16 lights, each sequence of four adjacent lights lit, so the cycle execution cycle direction can be controlled. Marquee design a controller. A total of eight lights, numbered LED0 ~ LED7, the lighting way: first left to right order of light, and then right to left, so the cycle and so on. These are all I stay up all night before the exam summary, very useful. When combined with the development board, then so much the better )
