High-speed design for mixed radix FFT algorithm based on multi-bank memory strategy

[摘要] References(14)A multibank memory structure is introduced for mixed radix FFT algorithms to improve the real-time performance. In this structure, only one butterfly unit implementing mixed radix butterfly computation is required and the FFT computation keeps continuous. At last, comparisons are made to prove that the method in this paper is valid.
