Electronic clock and simulation of VHDL procedures vhdl source code

说明：  学习VHDL可以用得上，有很多实例，可以对照着自己写一些东西(VHDL can be useful to learn, there are many examples, can be done to write something)

主要介绍了ＦＰＧＡ设计的基本原则、基本设计思想、基本操作技巧、常用模块。-Mainly introduces the basic principles of FPGA design, basic design concepts, basic operating skills, commonly used modules.

说明：  verilog 编写的ldpc编码，含有两个文件(LDPC written by Verilog)

低通滤波器在QUARTUS7.0开发环境下的文本与框图结合的实现方法的源代码-Low-pass filter QUARTUS7.0 development environment in the text and diagram combination of methods to achieve source code

基于FPGA的DDS程序代码，实现的功能强大可以输正弦波，三角波，方波等波形，并且频率可以调节。实现对应的功能强大。(FPGA-based DDS program code can achieve powerful output sine wave, triangle wave, square wave waveform and frequency can be adjusted. Implement corresponding powerful.)
