The Fast Fourier transform (FFT) algorithm with radix-2k is used to accomplish both a radix-2 butterfly and a minimize number with twiddle factor multiplication as Radix-2k delay feedback and radix-K delay commutators are the major well-known pipeline architecture for FFT design. To reduce the memory and area requirement here in this thesis we implemented a novel radix-24 multiple delay commutators called 4-Path Feedforward FFT architecture utilizes the advantage of the radix-2 algorithm.

The Fast Fourier transform (FFT) algorithm with radix-2k is used to accomplish both a radix-2 butterfly and a minimize number with twiddle factor multiplication as Radix-2k delay feedback and radix-K delay commutators are the major well-known pipeline architecture for FFT design. To reduce the memory and area requirement here in this thesis we implemented a novel radix-24 multiple delay commutators called 4-Path Feedforward FFT architecture utilizes the advantage of the radix-2 algorithm. By Combining the advantages of Radix-2 algorithm and feed-forward architecture, the proposed 4-Path radix-24 FFT processor achieves the least hardware requirement of multipliers and power consumption also reduced more when compared with Dual-path Radix-22 delay feedback FFT architecture. The entire FFT algorithms were implemented in Verilog hardware description language and synthesized with Xilinx I¿¿ design suit.
