基于nios2的花样灯

超前进位加法器

DESCRIPTION OF FULL ADDER

VHDL 的100例程代码，能够使你熟练掌握VHDL语言的编写(100 routines of VHDL code, enabling you to master the preparation of the VHDL language)

利用FPGA实现QPSK数字调制。编程采用Verilog HDL语言。(By using the FPGA realization of QPSK digital modulation. Use Verilog HDL language programming. )

FPGA控制DM9000A进行以太网数据收发的Verilog实现, 详细描述了DM9000A网络接口芯片的功能，对于DE2开发板上的学习很有帮助。还上载了C程序的实现以及Verilog 代码的实现，

说明：  Verilog 入门,如果你要很了解Verilog你不用先谖完一本厚厚的书还弄不清楚Verilog到底在干啥事,这份资料有助於快速了斛Verilog(Verilog Basic, If you try very hard to understand verilog by read a thick book, try read this first you will get a quick understanding of verlog.)

基于FPGA的希尔伯特变化的verilog代码(Hilbert change verilog code)

说明：  基于无源蜂鸣器和矩阵按键的电子琴系统设计(design of Electronic Piano System Based on Passive Buzzer and Matrix Key)

使用nios2点亮一个led灯，使用软件quartus13.0，开发板de2-115(nios2 led quartus13.0 de2-115)

基于RGMII的UDP网络数据通信，学习FPGA的千兆以太网通信(RGMII based UDP network data communication, learning FPGA Gigabit Ethernet communications)
