Digital Design and Modeling with VHDL and Synthesis

实现二项混合式步进电机的驱动，和步进电机的细分程序。(The driving of binomial hybrid stepper motor and the subdivision program of stepper motor are realized.)

代码用两种方法设计了一个基于多相滤波的内插器，低通滤波器采用128阶凯撒窗，内插倍数32，并且给定信号范围，验证了内插器的正确性，画出了内插前后信号的频谱。(The code design the interpolator based on polyphase filter using two methods.The low pass filter is 128 order Caesar window and interpolation multiple is 32.I give the range of the signal to verify the interpolator and plot the spectrum of the signal before and after the interpolator. )

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.
