    hum...

    actually, I haven't written FFT.

    but, I think there is IP cores.

    see, attached images.

    that is an FFT IP core.

    I also found an IP core, on opencores (http://opencores.org/)

    you can put real number to the real port.

    put imaginary number to the imaginary port.

    result will come to the output port as real and imagin.

    you don't have to know inside of IP core.

    back to my question.

    can you write HDL?
