We propose a novel FFT datapath that reduces the memory requirement compared to state-of-the-art RAM-based implementations by up to a factor of two. The novelty is in a technique to fuse the datapaths for the required perfect shuffle and bit reversal and is applicable to an entire design space of FFT implementations with varying degrees o...More
