PROJECT TITLE:

A Combined SDC SDF Architecture for Normal I/O Pipelined Radix-2 FFT - 2015

ABSTRACT:

We tend to gift an economical combined single-path delay commutator-feedback (SDC-SDF) radix-2 pipelined fast Fourier transform architecture, that includes log2 N - 1 SDC stages, and one SDF stage. The SDC processing engine is proposed to achieve a hundredpercent hardware resource utilization by sharing the common arithmetic resource in the time-multiplexed approach, including both adders and multipliers. Thus, the desired variety of complicated multipliers is reduced to log4 N - 0.five, compared with log2 N - one for the other radix-a pair of SDC/SDF architectures. In addition, the proposed design requires roughly minimum variety of complex adders log2 N + one and complex delay memory 2N + one.5log2 N - 1.five.
