Introducing ToPe‐FFT: An OpenCL‐based FFT library targeting GPUs
Concurrency and Computation: Practice and Experience, 2017SummaryIn this paper, we present our implementation of the fast Fourier transforms on graphic processing unit (GPU) using OpenCL. This implementation of the FFT (ToPe‐FFT) is based on the Cooley‐Tukey set of algorithms with support for 1D and higher dimensional transforms using different radices. Factorization for mix‐radices enables our code to target

Fast Fourier transform (FFT) algorithms based on the Cooley-Tukey approach [cf. \textit{J. W. Cooley} and \textit{J. W. Tukey}, Math. Comput. 19, 297-301 (1965; Zbl 0127.090)] are developed for single instruction multiple data (SIMD) machines. Any combination of FFT with powers of two as the periods and some alignment requirements for the initial data ...

Parallel Computing, 1987
Several vector component fast Fourier transforms (FFT) are developed for both shared and non-shared multiprocessors. The focus is mainly on the efficiency of the movement of data. First eight FFTs algorithms are reviewed and then they are used to develop two FFTs for vector multiprocessors with shared memory.

A 2-D FFT-Based Transceiver Architecture for OAM-OFDM Systems With UCA Antennas
IEEE Transactions on Vehicular Technology, 2018Radio orbital angular momentum (OAM) provides another perspective of spatial multiplexing to improve the spectrum efficiency. However, multipath induces severe intra- and interchannel crosstalk.

A Variable-Size FFT Hardware Accelerator Based on Matrix Transposition
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2018Fast Fourier transform (FFT) is the kernel and the most time-consuming algorithm in the domain of digital signal processing, and the FFT sizes of different applications are very different.

Methods are presented for developing synthesisable FFT cores. These are based on a modular approach in which parameterisable blocks are cascaded to implement the computations required across a range of typical FFT signal flow graphs. The underlying architectural approach combines the use of a digital serial data organisation with generic commutator ...

In this paper, an efficient implementation of the Continuous Flow 2N point Real to Complex FFT is presented. The computation is based on the Radix-2 version of Cooley-Tukey algorithm. The key feature of this implementation is the alternation between DIF (Decimation In Frequency) and DIT (Decimation In Time) in the computation of FFT and IFFT of ...
