48-Mode Reconfigurable Design of SDF FFT Hardware Architecture Using Radix-32 and Radix-23 Design Approaches


In this paper, we propose a reconfigurable (RC) fast Fourier transform (FFT) design in a systematic design scheme. The RC design bricks are mainly proposed to arbitrarily concatenate to support FFT-point required. Meanwhile, we show three developed design techniques, including six-type RC processing element, systematic first-in first-out reuse arrangement… (More)
