键盘计算器，可实现加减乘数运算 基于fpga nios2(Keyboard, calculator, addition and subtraction can be realized based on fpga nios2 multiplier operator)

verilog设计的32位IO口扫描后通过串口发送到计算机(Verilog design of 32 bit IO export after scanning through the serial port to the computer)

open cores 提供的i2c控制IP核 可直接在FPGA上使用。并带有相关的测试程序(endorsed by the i2c controller IP provided by the open cores on the FPGA. With the relevant test procedures)

说明：  使用Verilog，以Quartus II 为平台，编写了一个DDS信号发生器程序。(Using Verilog and Quartus II as the platform, realizing the DDS signal generator program .)

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.)
