国外经典verilog代码，很适合初学者，其中的有些概念对老手也可以考虑下...

一个求反余弦的cordic算法，整个工程。包括仿真。可以直接打开。(An inverse cosine of the cordic seeking algorithms, the whole project. Including the simulation. Can be directly opened.)

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.)
