High-Speed Data Serialization and Deserialization(840 Mb/s LVDS) for xilinx fpga

FPGA中实现的MSK调制，带modelsim仿真。实际系统测试通过：载波和调制波信号频率可调。调制框图请参见樊昌信 通信原理247页(MSK modulation implemented in FPGA with modelsim simulation. The actual test system: a carrier wave signal and the modulation frequency is adjustable. See Fan Changxin modulation block diagram of communication theory 247)

本文以 VHDL 语言编码得到了 AMBA 与 AHB 总线仲裁。这里在本文中，我们设计了 AMBA 总线协议，将用于多奴隶通信环境，多主

为了便于计算结果在FPGA中后续的计算和ip核中的调用，本代码输入信号为普通浮点型数据，输出为32位表示的浮点型数据。

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.)
