VLSI Design of Pipelined FFT Architecture for DSP Application

This study proposes a novel method for implementing multiplier-less single-delay feedback with one gain The quick Fourier transform (FFTs). The earlier techniques use either complex multipliers or non-unity to produce unity-gain FFTs. extra scaling compensation in gain rotators. By jointly designing rotators, it is possible to get unitygain FFTs even while employing non-unity-gain rotators. This allows the FFT and IFFT to be mount by power of two and next resort to unity. This can lessen amount of components resource of FFT. Verilog HDL and Modelsim 6.4 can be used to implement and simulate the suggested FFT and IFFT techniques. Finally, it was synthesized using a Xilinx tool, implemented on a Spartan 3 FPGA XC3S 200 TQ-144, and entire blueprint was checked for theoretical results using System Verilog HDL.
