VHDL语言实现PWM信号，非常方便的使用

设计一个由一条主干道和一条支干道的汇合点形成的十字交叉路口的交通灯控制器： 1)       主、支干道各设有3个方向的绿、黄、红指示灯（左转、直行和右转），每个行驶方向均配有时间显示数码管；2)       主干道处于常允许通行状态，而支干道有车来才允许通行（由外部信号通知）。3)       当主、支道均有车时，两者交替允许通行，主干道每次放行90s，支干道每次放行60s，在每次由亮绿灯变成亮红灯的转换过程中，要亮5s黄灯作为过渡，并进行减计时显示。

这个是DE2上的SDRAM 四个端口的驱动代码，相当实用！(This is a four-port SDRAM on a DE2 driver code, very useful!)

使用verilog实现全数字16QAM调制器，载波频率1MHZ，数据比特流的速率为100Kbps,(the modulation of 16QAM based on FPGA)

本源码为Nios II的开发示例,主要演示Nios II的定时中断器的应用。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。-The source code for the Nios II development of an example, the main demonstration Nios II interrupt timing device applications. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through

verilog语言实在点变换DFT源代码，可以配合软核或者其他CPU进行综合FFT变换，也可以单独使用生成module！(verilog language is point FFT transform source code, can tie in with the soft-core CPU, or other integrated FFT transform, it can be used to generate module!)

FPGA学习的非常好的资料，希望广大朋友都可以学习学习啊(FPGA to learn very good information, I hope our friends can learn ah)

用verilog HDL编写的SPI控制器，从国外网站上找到的。-SPI (Serial Peripheral Interface) is serial, synchronous, full duplex communication protocol. It is widely used as a board-level interface between different devices such as microcontrollers, DACs, ADCs and others.

光纤通道协议，包括FC-SW,FC-FS,FC-LS,FC-GS,FC-HBA,FC-AE-ASM等文档。 (Fibre Channel protocols, including FC-SW, FC-FS, FC-LS, FC-GS, FC-HBA, FC-AE-ASM and other documents.)(Fiber channel protocol, including FC-SW, FC-FS, FC-LS, FC-GS, FC-HBA, FC-AE-ASM and other documents. (Fibre Channel protocols, including FC-SW, FC-FS, FC-LS, FC-GS, FC-HBA, FC-AE-ASM and FC-AE-ASM))

Verilog使用automatic function的範例(Verilog example of the use of the automatic function)
