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.)

verilog产生高斯白噪声，gwn_en信号产生使能，gdata是幅度服从高斯分布，功率谱密度为定值的高斯白噪声序列，共10位（现实中只能够做到带限，跟dac输出带宽有关，我的系统只能做到300kHz）(verilog Gaussian white noise, gwn_en signal enabled, gdata amplitude Gaussian distribution, power spectral density of white Gaussian noise sequence value, a total of 10 (in reality can only be band-limited, with dac output bandwidth related, My system can do 300kHz))

sp605_multiboot_rdf0028_13.2_c 主要进行ICAP内部配置，在mutlboot中使用内部接口ICAP，通过state machine 控制ICAP读取 寄存器的状态值。还需要进行bit swap 对指令进行位交换

本代码是cache代码，采用最近最少使用算法。代码量大约1000-2000行，程序包括cache替换算法的实现。映像规则的选择，以及全部的仿真程序。
