Re: [oc] New! FFT core

[sradio@opencores.org]

Iin is real part of the input complex sequence, while Qin is the image 
part of the input complex sequence.

You sould pay attension to the ouput order, which is radix 4 reversed 
order. And Iout is read part of the output complex sequence, while 
Qout is the image part of the output complex sequence.

If I have sufficient time, I will write an another test bench.

Sorry to confuse you.

Good luck.
