The Fast Fourier Transform (FFT) is a very common DSP function used to convert
samples in the time domain to and from the frequency domain. A fundamental
building block of the FFT is the FFT butterfly. FFTs are most efficient when operating
on complex samples. You can use the Stratix III DSP block to form the core of a
complex FFT butterfly very efficiently.
