nios_ruanhe_spi_3
这是我自己写的一个摄像头数据存储SD卡程序，quartus的verilog编写，摄像头采用自己添加的外设接口，数据采用dma采集，SD用的是软件自带的SPI内核以及znFAT的文件系统。帧率我没有测，有兴趣的可以测测，初学者可以参考学习，写的代码有点乱，如果有不懂的可以和联系。(This is what I wrote it myself a camera, SD card data storage program, quartus the verilog write, add their own camera with peripheral interfaces, data acquisition using dma, SD with the software that comes with SPI znFAT kernel and file system. I did not measure the frame rate, are interested can Cece, beginners can refer to the study, wrote the code a bit messy, if there do not understand can contact)

xilinx_dna_read
该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)
