Reconfigurable FFT System on Chip (SOC)
With on-set 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 the authors propose a reusable FFT using reconfigurable multiplier. However, the FFT perform both 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.
