Using VHDL realize the divider, so very, simulation adopted

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.

本练习的目的是构建和使用计数器。所设计的电路将在计算机上实现

递增方式在4位数码管上向上计数显示从0000-0001->0002……..9999….0000….0001…. -- 利用CPLD设计了一个4位十进制计数器，并用数码管显示当前计数值-Incremental approach in the four counts upward digital tube display from 0000-0001-

4tap FIR filter in verilog code

this example finds the gapes that are existed in a word

利用stm32F407实现的等精度测频，可以精确测量频率，误差很小(The equal precision frequency measurement realized by stm32F407 can accurately measure frequency with little error.)
