本文为通信专业硕士研究生的毕业论文。主要研究神经网络的FPGA实现及其在网络拥塞控制中的应用。 (In this paper, for the communications professional Master s thesis. Major study of the FPGA realization of neural networks and its application in network congestion control applications.)

verilog代码，串口发送接收代码，含有源代码和测试文件，准确可用(verilog code for serial port transmit and receive code, with source code and test files, and accurate available)

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.)

说明：  verilog语言书写，单周期CPU源码(single period CPU)
