A High-Entropy True Random Number Generator with Keccak Conditioning for FPGA
Published on 2025-03-08 by Valeria Piscopo, Alessandra Dolmeta, Mattia Mirigaldi, Maurizio Martina, Guido Masera @MDPI
Abstract: Any cryptographic system strongly relies on randomness to ensure robust encryption and masking methods. True Random Number Generators play a fundamental role in this context. The National Institute of Standards and Technology (NIST) and the Bundesamt für Sicherheit in der Informationstechnik (BSI) provide guidelines for designing reliable entropy sources to fuel cryptographic Random Bit Generators. This work presents a highly parameterized, open-source implementation of a TRNG based[...]

Research on Approximate Computation of Signal Processing Algorithms for AIoT Processors Based on Deep Learning
Published on 2025-03-07 by Yingzhe Liu, Fangfa Fu, Xuejian Sun @MDPI
Abstract: In the post-Moore era, the excessive amount of information brings great challenges to the performance of computing systems. To cope with these challenges, approximate computation has developed rapidly, which enhances the system performance with minor degradation in accuracy. In this paper, we investigate the utilization of an Artificial Intelligence of Things (AIoT) processor for approximate computing. Firstly, we employed neural architecture search (NAS) to acquire the neural network structure [...]
Our summary: Research investigates approximate computation of signal processing algorithms for AIoT processors based on deep learning. Neural architecture search is employed to acquire the neural network structure for approximate computation, which approximates functions of FFT, DCT, FIR, and IIR.

Accelerating Pattern Recognition with a High-Precision Hardware Divider Using Binary Logarithms and Regional Error Corrections
Published on 2025-03-07 by Dat Ngo, Suhun Ahn, Jeonghyeon Son, Bongsoon Kang @MDPI
Abstract: Pattern recognition applications involve extensive arithmetic operations, including additions, multiplications, and divisions. When implemented on resource-constrained edge devices, these operations demand dedicated hardware, with division being the most complex. Conventional hardware dividers, however, incur substantial overhead in terms of resource consumption and latency. To address these limitations, we employ binary logarithms with regional error correction to approximate division operation[...]
Our summary: Accelerating pattern recognition with a high-precision hardware divider using binary logarithms and regional error corrections, reducing hardware complexity and minimizing errors, implemented on a Zynq UltraScale+ FPGA platform.
