EDA设计 交通灯

由Verilog编写在FPGA实现sobel算法应用于图像边缘检测，工程文件可在quartus13.1以上版本打开；工程使用到ram、fifo、pll三种ip核，design文件夹下包含ram、fifo、vga控制以及串口收发和sobel算法模块，sim和doc文件夹下分别包含modelsim的仿真模块和仿真结果；测试时将200*200分辨率的图片用matlab文件夹下的matlab脚本压缩、二值化，再将生成文件中数据用串口发给FPGA，边缘检测结果会通过VGA输出。(Written by Verilog in the FPGA implementation sobel algorithm applied to the edge detection of the image, the project file can be opened in the quartus13.1 or later project use ram, fifo, pll three ip kernel, design folder contains ram, fifo, vga control and Serial port transceiver and sobel algorithm module, sim and doc folder, respectively, include modelsim simulation module and simulation results test will be 200* 200 resolution picture matlab folder under the matlab script compression, binarization, and then generated Data in the file with the serial port to the FPGA, edge detection results will be output through the VGA.)

32位二进制除法器2

基于ＦＰＧＡ，实现了移位除法的功能，程序接口简单，十分好用，已经验证。-Based on the FPGA, to achieve the division of functional shift, the program interface is simple, very easy to use, has already been verified.

常用的VHDL语言编写的LED灯控制程序,这是教学用的，开发板采用的是EPM240T100C5N，买开发板时附带的程序

基本的操作代码,a0-a7是八个信号输入端，a7的优先级最高，a0的优先级最低，当a7输入低电平0时，其他输入无效，编码输出y2y1y0=111；如果a7无效，而a6有效，则y2y1y0=110；
