XILINX FPGA on internal training materials in Chinese

层合板的刚度的计算和验算，包括拉伸刚度A、弯曲刚度D以及耦合刚度B。 首先要给定层合板的各个参数，具体有：层合板的层数N；各单层的弹性常数E1、E2、 、G12；各单层对应的厚度；各单层对应的主方向夹角 。(The stiffness of laminated plates is calculated and checked, including tensile stiffness, A, flexural stiffness, D and coupling stiffness B. First of all, it is necessary to give the parameters of laminated plates, such as the number of plies N, the elastic constants of each layer, E1, E2, and G12, the thickness of each monolayer, and the angle of the main direction corresponding to each single layer.)

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)

Verilog代码实现Sobel算子，包括整个工程，仿真也有。。仿真表明该程序能实现Sobel 算子硬件实现(Verilog，Sobel Operator)

一个简易的频率计，主要用检测在一定范围内的频率，当然频率过大会有误差(A simple frequency meter, mainly used for testing in a range of frequencies, of course, frequency of errors over the General Assembly)
