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)

说明：  资料是本人根据相关文献资料用vhdl语言编写的旋转机械鉴相信号倍频的程序，multifre1.vhd是倍频程序，multifre1.vwf是仿真波形文件，stp1.stp是虚拟逻辑分析仪signaltap文件。该倍频程序可以直接使用，可以设置倍频数，修改实体参数N即可。(According to the literature data is the information I have written in with vhdl Rotating Machinery Kam believe that the procedure multiplier number, multifre1.vhd is the multiplier process, multifre1.vwf is the simulation waveform files, stp1.stp a virtual logic analyzer signaltap file. The multiplier process can be used directly, you can set the multiplier number, modify the parameter N can be solid.)

数控分频器的设计数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。-NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different sub-frequency ratio, NC prescaler value can be used include parallel preset counter adder design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.
