fft_fpga_dit
Decimation-In-Time Fast Fourier Transform
I"ve tried to make the implementation simple and well documented.
I have not tried to make it efficient.
dit.v - Contains main module.
buffer.v - Contains a module for a single butterfly step.
generate_twiddlefactors.py - Contains function to generate a verilog file with twiddlefactors.
twiddlefactors_N.v.t - Template used to generate verilog file.
dut_dit.v - A wrapper around the "dit" module to allow verification with MyHDL.
qa_dit.py - A MyHDL test bench for verification.
Requires MyHDL, iverilog and numpy to be installed.
pyfft.py - Generates output of intermediate FFT stages. Useful for debugging.

5位计数器
应用背景计数器是一个连续的电路，计数。这意味着它的收益通过一个预先定义的序列的状态的电路的状态是由所有的触发器的状态决定的。最基本的计数器将只增加1的每一个时钟脉冲，所以状态100将达到101，下一个脉冲将让它切换到110这是可能的设计与任何需要计数的计数器序列。关键技术频率计数器数字钟时间测量模数转换器分频电路数字三角波发生器。
