FFT Implementation in C

This repository contains two implementations of the Fast Fourier Transform (FFT) algorithm in C: a sequential version and a parallel version using OpenMP.

Folder Structure

• sequential-fft: Contains the sequential FFT implementation targeting the ARM Cortex-A9 processor on the Zynq-7000 All Programmable SoC.
• parallel-fft: Contains the parallel FFT implementation optimized using OpenMP for improved performance.

Sequential FFT

• Implements the Cooley-Tukey radix-2 decimation-in-time (DIT) FFT algorithm.
• Targeted for the ARM Cortex-A9 processor on the Zynq-7000 All Programmable SoC.
• Build and run instructions are provided in the sequential-fft folder.

Parallel FFT using OpenMP

• Implements the Cooley-Tukey radix-2 DIT FFT algorithm with OpenMP parallelization.
• Supports both forward and inverse FFT computations.
• Requires a C compiler with OpenMP support (e.g., GCC) and C99 standard or later.
• Usage instructions are provided in the parallel-fft folder.
