关于DFT的文章，应用FPGA实现傅立叶变换。-Abstract—We present a domain-specific approach to generate high-performance hardware-software partitioned implementations of the discrete Fourier transform (DFT). The partitioning strategy is a heuristic based on the DFT

实现分频功能，用VHDL语言实现，也可适当改变参数，实现任意分频-Implementation divider using VHDL, it may be appropriate to change the parameters to achieve any divide
