HC-FFT: highly configurable and efficient FFT implementation on FPGA
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2021 FFT is one of the basic building blocks in many applications such as sensors, radars, communications. For some applications, e.g., real-time spectral monitoring and analysis, FFT needs to be”run-time configurable” so that the system is real-time. When examining the previous work on configurable real-time (FPGA-based) FFT implementations, we see that ...

IEEE Transactions on Circuits and Systems II: Express Briefs, 2016 This brief presents a new type of fast Fourier transform (FFT) hardware architectures called serial commutator (SC) FFT. The SC FFT is characterized by the use of circuits for bit-dimension permutation of serial data. The proposed architectures are based on the observation that, in the radix-2 FFT algorithm, only half of the samples at each stage must ...

, 1994 We propose two families of scalable hash functions for collision-resistant hashing that are highly parallel and based on the generalized fast Fourier transform (FFT). FFT-hashing is based on multipermutations. This is a basic cryptographic primitive for perfect generation of diffusion and confusion which generalizes the boxes of the classic FFT.

Enhancement of Fingerprint Using FFT×|FFT|n Filter
Procedia Computer Science, 2015 AbstractFingerprint enhancement is an indispensable task in the Automatic Fingerprint Identification System. In this paper, a simple method for the enhancement of fingerprint images is presented, which is based on FFT. The FFT is found out after the fingerprint image is partitioned into blocks.

A simple extension of FFT-based methods to strain gradient loadings - Application to the homogenization of beams and plates with linear and non-linear behaviors [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2022 Because of their simplicity, efficiency and ability for parallelism, FFT-based methods are very attractive in the context of numerical periodic homogenization, especially when compared to standard FE codes used in the same context. They allow applying to

International Journal of Population Data Science, 2023 We examine the post age-16 educational pathways taken by the 44% of young people who do not gain “good” grades in English and Maths at age 16 years. We then assess the causal effects of attending General Further Education (GFE) colleges on education and
