VHDL的例子很多，没有试验，供大家参考

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)

说明：  altera fpga 实现fft，用fft IP核，有matlab仿真代码(Altera FPGA implementation of FFT, FFT IP core, matlab simulation code)

说明：  基于fpga的函数发生器设计通过fpga实现正弦波输出(基于fpga的函数发生器)

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

这个我弄了好久，伤心了。不过，自己喜欢，终于把他给做了出来，过程是相当的复杂，不信。你们可以下下来看看，有不懂得可以咨询我
