Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Abstract: This paper implements the Fast Fourier Transform (FFT) algorithm for signal data processing using Open Computing Language (OpenCL). A parallel algorithm model suitable for staged FFT across ...

Turbine Testing Lab, Department of Mechanical Engineering, Kathmandu University, Dhulikhel, Nepal Hydro turbines are prone to failure and the detection of fault in turbine is essential to ensure the ...

Being done in PipelineC it's possible to automatically pipeline both the math of some RISC-V instructions as well as the arbitrary pure functions that describe the custom compute pipelines attached to ...

Fourier transform is a key method for analyzing signals in both time and frequency domains. The FFT is a computational algorithm that efficiently computes the discrete Fourier transform (DFT) and its ...

Real-valued convolutional neural networks (RV-CNNs) in the spatial domain have outperformed classical approaches in many image restoration tasks such as image denoising and super-resolution. Fourier ...

In part 2 of this series, we looked at a swept-tuned spectrum analyzer and how it could sweep a frequency span of interest from 1 MHz to 1.1 MHz with a sweep time of 50 msec. As Figure 1 shows, the ...

Fast Fourier transform (FFT) using the Cooley–Tukey algorithm for power-of-two sizes and Bluestein's algorithm for non-power-of-two sizes.
