用来实现IRIG_B码的解码程序，在XILINX ISE上运行过没有问题，(Used to achieve IRIG_B code decoding process, in XILINX ISE run-off is no problem,)

说明：  32位/33M 从模式(target)PCI接口参考设计，Lattice提供。由于PCI时序较复杂，此设计仅能供参考(32/route from the model (target) PCI reference design, Lattice provided. Because PCI timing more complicated, and the design for reference only)

超低速的光纤一体发接收发送器,同于以前的光纤一体化接头都只适用于2M以上的通讯,如需将232等低速信号用光纤传输出,需要加复杂的调制解调电路,网动光电新生产的这款光纤头主要针对低速信号,可以传送DC-500KPS的信号,极大地简化了硬件设计.(Ultra-low-fat whole-speed fiber-optic transmitter receiver with fiber-optic integration in the previous joint only applies to more than 2M communications, etc. For the 232 low-speed optical fiber transmission of signals, the need to increase the complexity of the modulation and demodulation circuit, the net move Photoelectric new production of this first major response to low-speed fiber-optic signal, DC-500KPS can send the signal, greatly simplifying the hardware design.)

基本交通系统,实现城市交通路口的模拟仿真，自己的课程设计作品(Basic transport system, urban traffic junction simulation, design their own courses)

说明：  使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)
