基于FPGA的实现小数倍分频代码，广泛应用于数字通信中。

vhdl,双向移位寄存器，实现置数，左移及右移操作-vhdl, bi-directional shift register to achieve set the number of left and right shift operation

AD0832 AD转换程序，功能完全通过测试，备注非常详细，KEILC编程，通用性强(AD0832 AD converter, fully functional test, notes, very detailed, KEILC programming, versatility)

该程序描述了运用FPGA进行控制的S形曲线和其他传统加减速控制曲线方法的控制曲线比较研究。(This program is compiled in matlab circumstance。Describing the approach of S-curve control method in FPGA in machine controlling.)

介绍了硬件语言的仿真软件modelsimse的操作是使用方法，可以为入门的参考资料-Introduction of the hardware language modelsimse operation simulation software is to use the method of reference for the entry

AGC(自动增益放大) Verilog代码 设计可以参考(AGC (automatic gain control) can refer to the Verilog code design )

说明：  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.)

数控分频器设计:对于一个加法计数器，装载不同的计数初始值时，会有不同频率的溢出输出信号。计数器溢出时，输出‘1’电平，同时溢出时的‘1’电平反馈给计数器的输入端作为装载信号；否则输出‘0’电平。 -NC divider design : an adder counter, loading the initial count value, have different frequency output signal of the overflow. Counter overflow, the output"1 "Level, Overflow at the same time the"1 "level feedback to the counter input signal as loading; Otherwise output"0 "level.

是我们在在实验室做的摸60计数，并用LED显示出来。-is done in the laboratory in the loss of 60 counts, and LED show.

通信系统的FSK调制程序，比较实用，包括完整的工程-FSK modulation communication system procedures, more practical, including the complete works
