Reconfigurable FFT System on Chip (SOC)
G. Venkataramana Sagar, Karumuri Srinivasa Rao · International Journal of Computer Applications · 2010
With onset of paradigms of System On Chip (SOC) to design a module for real time applications or voice codec"s, The SOC"s have different requirements for operands precision we propose a reusable FFT [2] using reconfigurable multiplier [6].How ever, the FFT perform either combining N and N/2 bit multiplications in the same N bit tree multiplier.The key challenges in designing a reusable FFT are to limit the impact of flexibility on power operations that are needed for FFT butterfly to perform better than a conventional, dedicated FFT butterfly.
