简易数字存储示波器verilog源代码 经过EP2C8Q208C8验证(Simple digital storage oscilloscope verilog source code has been verified EP2C8Q208C8)

AD768产生锯齿波的源码，DA转化的最基本操作。(AD768 sawtooth source code, the basic operation of DA conversion.)

quartus II 13.0 DDS工程文件，采用VHDL编写，可输出正交两路正弦信号。可以直接用modelsim-alter 仿真(quartus II 13.0 DDS project file, using VHDL written two orthogonal sinusoidal output signals. Can be simulated directly modelsim-alter)

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.)
