vhdl例程代码大全，包含流水灯，数码管，AD,DA转换等(Guinness vhdl code routines, including water lights, digital, AD, DA conversion)

计数器是数字系统中使用最多的时序电路，它不仅能用于对时钟脉冲计数，还可以用于分频、定时、产生节拍脉冲和脉冲序列以及进行数字运算等。(Counter is the most frequently used sequential circuit in digital system. It can be used not only for counting clock pulses, but also for frequency division, timing, generating beat pulses and pulse sequences, and performing digital operations.)

fir filter 程序 老师上课留的作业，在这里跟大家分享一下，希望能有所帮助(fir filter procedures teacher in the class to stay the operation here to share with you, hope can be helped)

本人编写的FPGA光电编码器输入模块,没有实验,但仿真基本实现,希望有参考价值.(FPGA optical encoder input module, there is no experimental, but simulation technology, hope to have reference value.)
