CIC抽取滤波器，抽取系数8,verilog版本，用于数字下变频(CIC decimation filter, extraction coefficient of 8, verilog version, for digital down-conversion)

verilog编写的SDRAM实验，有串口调试助手和相关资料！！！！！！！！！！！！！！！！！！！！！(Verilog prepared by the SDRAM experiment, a serial debugging assistant and related information!!!!!!!!!!!!!!!!!!!!!)

基于ALINX AX7020硬件平台的USB-OTG通信程序。操作系统采用uCOS III v1.41，基本实现了双向USB2.0 块传输（Bulk Transfer）通信，zynq的PS端接收USB数据并回传至主机。经测试，主机端Window10系统采用libUSBK编程时，采用64字节的块时，传输速率可达210Mbps。zynq开发工具为Vivado2015.4，程序包中包含了全部的硬件和软件工程文档。(A USB-OTG communication project where an AX7020 platform is employed as USB device. The embeded operating system is uCOS III of version 1.41, and the FPGA toolchain is Vivado 2015.4. This project implements a full speed bidirectional USB2.0 bulk transfer. A test on Windows 10 host with libUSBK shows that the transfer speed is up to 201Mbps.)

基于verilog语言的差分曼彻斯特编码，内包含数据的采集，CRC校验（8位），和编码，输出。附有完整的工程文件。可直接调用modelsim仿真。(Based on differential Manchester encoding verilog language, and contains data collection, CRC check (8), and coding. With complete project file. Modelsim simulation can be called directly.)

速度表（velocity）要求：1．显示汽车Km/h数；2．车轮每转一圈，有一传感脉冲；每个脉冲代表1m的距离；3．采样周期设为10s； 4．要求显示到小数点后边两位；5．用数码管显示；6. 最高时速小于300Km/h。（约为83.3m/s） (use verilog to realize velocity)

quartusii 三分频电路，大家帮参考一下，有什么问题-one-third of quartusii frequency circuit, refer to U.S. help, have any problem
