Altera clearly mentions that their pipelined FFT core uses R2^2SDF architecture. But I could not find any such info about Xilinx -- can anyone help?

I guess Xilinx also uses R2^2SDF --- because they have scaling for every pair of radix 2 butterflies.> >Altera clearly mentions that their pipelined FFT core uses R2^2SDF >architecture. >But I could not find any such info about Xilinx -- can anyone help? > >Onkar > >>Hi, >> >>Can anyone tell me whether the Xilinx Pipelined FFT arch uses R2SDF or >>R2^2SDF? >> >>Regards, >>Onkar >> >> >> >>--------------------------------------- >>Posted through http://www.FPGARelated.com >> > >--------------------------------------- >Posted through http://www.FPGARelated.com >--------------------------------------- Posted through http://www.FPGARelated.com
