一个用VHDL语言编写的双端口存储器程序，可下载在FPGA中使用

一个走马灯的程序,可以按照要求一个一个往后面按顺序点亮(A program for the lantern can be lit one by one according to the requirements.)

说明：  用Verilog编写的简单的运算单元（ALU），可实现加、减、与、或、异或、非、左、右移等功能(Verilog prepared with simple arithmetic unit (ALU), can be add, subtract, and, or, exclusive-OR, non-, left, and other functions shifted to right)

VHDL实例这是我下载到的最好的VHDL实例，看完这些实例，可以使你有一个长足的进展-VHDL example

verilog仿真硬件的工具qiartus2的使用教程,内容简单易懂,初学必备(Verilog simulation tool for hardware qiartus2 the use of tutorials, easy-to-read content, learning essential)

说明：  基于ALINX AX7020硬件平台的USB-OTG通信程序。操作系统采用uCOS III v1.41，基本实现了双向USB2.0 块传输（Bulk Transfer）通信，zynq的PS端接收USB数据并回传至主机。经测试，主机端Window10系统采用libUSBK编程时，采用64字节的块时，传输速率可达210Mbps。zynq开发工具为Vivado2015.4，程序包中包含了全部的硬件和软件工程文档。(A USB-OTG communication project where an AX7020 platform is employed as USB device. The embeded operating system is uCOS III of version 1.41, and the FPGA toolchain is Vivado 2015.4. This project implements a full speed bidirectional USB2.0 bulk transfer. A test on Windows 10 host with libUSBK shows that the transfer speed is up to 201Mbps.)

利用VHDL 硬件描述语言设计一个0~9999 的加法计数器。根据一定频率的触发 时钟，计数器进行加计数，并利用数码管进行显示，当计数到9999 时，从0 开始重新计数(Use of VHDL hardware description language design a 0 ~ 9999 addition counter. According to a certain frequency of the trigger The clock, counter add count, and use digital pipes to show that when the count to 9999, starting from 0 to count )

sobel边缘检测，用于图像处理。实现了该算法在FPGA上的实现代码。(Sobel edge detection for image processing.Implementation of the algorithm to achieve the FPGA code.)

此为数学形态滤波器消燥的代码，用于一维信号，涉及一个具体的例子，需要的话可以自己修改，修改相应的结构元素。(This is a mathematical morphology filter away dry code, used to one dimensional signal, involving a concrete example, necessary can change ourselves, change the structure of the corresponding elements)

costas的verilog程序，包含乘法器，DDS，鉴相器，环路滤波器等模块(costas the verilog program, including multipliers, DDS, phase detector, loop filter modules)

基于fpga的多功能电子钟的设计非常使用希望对大家有帮助啊-FPGA-based multi-functional electronic clock design to use would like to help everyone ah
