只需要FPGA两个通用管脚，就可以实现FPGA与PC机进行以太网通信！！如果你有ALTERA_DE1的开发板，可以直接下再看效果，用其他板子就要重新分配一下管脚，推荐使用电流输出。-Only two general-purpose FPGA pins, you can realize FPGA and Ethernet PC machine! ! If you have ALTERA_DE1 development board, you can look under the direct effect, with other board you will need to reconsider the distribution of pins, recommended the use of current output.

实光电码盘的输出数据的四倍频，使码盘输出精度提高四倍。-real photoelectric encoder output data of the four frequency, accuracy encoder output increased by four times.

用VHDL编写的huffman编码的源程序(With the VHDL source code written in huffman coding)

基于状态图的光电编码器4倍频vhdl程序，输入相位差90度的两相，输出倍频和方向信号-Based on the state of the optical encoder Figure 4 multiplier vhdl procedure, enter a 90-degree phase difference of two-phase, frequency and direction of the output signal

用FPGA实现sos摩尔密码，即输出电平信号短长短。就是有次序的控制输出莫斯密码的“点”，“画”和“间隔”。而 control_module.v 是一个简单的定时触发器，每一段时间都会使能sos_module.v。(Realized by FPGA sos mole password, the output signal level of short duration. There is a sequence of output control points Moss password, painting and intervals. And control_module.v is a simple timer triggers, each period of time will enable sos_module.v.)

用FPGA实现pwm调制波，通过单片机软核控制输入量来实现任意占空比方波的产生-wave

图像滤波中的中值滤波，有效滤除椒盐噪声，使用verilog语言编写(Image filtering in the median filter, effectively filter out salt and pepper noise, using verilog language)
