About 1588 PTP protocol xillinx FPGA running code and Software application, and to introduce documents, want to help everyone

用VHDL实现了希尔伯特滤波器,即就是幅度不变，而相位移动90度(use vhdl to accomplish the hilbert filter)

FPGA中按键弹跳消除模块的研究与应用，原理和例子都非常好-FPGA to eliminate bounce in key research and application modules, principles and examples are very good

RS(255,223)编码器程序 从一本书上看到的，很不错的(RS(255,223) encode , very good good good )

TD-LTE中（3.1.7）咬尾卷积码编码器verilog代码(Tail-biting convolutional code encoder verilog code)

基于FPGA的交通灯的设计 有Verilog HDL 源码、仿真图与引脚配置图，已下载实现 -FPGA-based design of traffic lights have Verilog HDL source code, simulation map with pin configuration map has been downloaded realize

数字频率测量器，脉宽测量器。可测量多种频率波形的脉宽。(Digital frequency measurement device, pulse width measurement device. Measurement of the waveform of frequency pulse width)

数字频率计，测量范围0-1GHZ,测周测频自动转换，精度极高，花了很长时间，不过还是有一点点小问题，有待改进.(Digital frequency meter, range 0-1GHZ, automatic conversion measured weekly frequency measurement, high precision, took a long time, but still a little small problems to be improved.)
