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.)

Rst是低电平有效的系统复位信号，Clk是时钟信号。AB[5：0]是地址信号，DB[7：0]是数据信号，wr是低电平有效的写信号。start是启动信号。 模块中有一个64x8的双端口的存储器。系统复位结束后，可以通过AB、DB和wr信号向同步存储器写入数据。当写入64个数据后，给出一个Clk周期宽度的脉冲信号start，则系统从存储器0地址处开始读出数据，读出的8位数据从低位开始以3位为一组，每个时钟周期输出一组，即第一个时钟周期输出[2：0]位，第二个时钟周期输出[5：3]位，第三个周期输出1地址的[0]位和0地址的[7：6]位，直至将存储器中64x8数据全部输出。若最后一组不足三位，则高位补0。 (Rst is an active-low system reset signal, Clk is a clock signal. AB [5: 0] is the address signal, DB [7: 0] is the data signal, wr write signal is active low. start is the start signal. Module in a dual port memory of 64x8. After the reset, you can write data to the synchronous memory by AB, DB and wr signals. When data is written to 64, given the width of a pulse signal Clk cycle start, the system begins to read the memory address 0, 8 data read out a low starting with three as a group, each clock outputs a set period, which is the first clock cycle of the output [2: 0] bits, the second clock cycle output [5: 3] position, the third cycle of the output of an address [0] and 0 address [7 : 6] bit, until all the data in memory 64x8 output. If the last group of less than three, the high 0s.)
