Evaluating critical bits in arithmetic operations due to timing violations [PDF]
, 2017 Various error models are being used in simulation of voltage-scaled arithmetic units to examine application-level tolerance of timing violations. The selection of an error model needs further consideration, as differences in error models drastically ...

High-Precision Arithmetic in Mathematical Physics
Mathematics, 2015 For many scientific calculations, particularly those involving empirical data, IEEE 32-bit floating-point arithmetic produces results of sufficient accuracy, while for other applications IEEE 64-bit floating-point is more appropriate.

TWFalcon: Triple-Word Arithmetic for Falcon
Transactions on Cryptographic Hardware and Embedded SystemsThe post-quantum signature scheme Falcon is an attractive scheme for constrained devices due to its compactness and verification performance. However, it relies on floating-point arithmetic for signature generation, which - alongside physical security ...

Lightweight Floating-Point Arithmetic: Case Study of Inverse Discrete Cosine Transform
EURASIP Journal on Advances in Signal Processing, 2002 To enable floating-point (FP) signal processing applications in low-power mobile devices, we propose lightweight floating-point arithmetic. It offers a wider range of precision/power/speed/area trade-offs, but is wrapped in forms that hide the ...

Algorithms for Manipulating Quaternions in Floating-Point Arithmetic [PDF]
2020 IEEE 27th Symposium on Computer Arithmetic (ARITH), 2020 Quaternions form a set of four global but not unique parameters, which canrepresent three-dimensional rotations in a non-singular way. They arefrequently used in computer graphics, drone and aerospace vehiclecontrol. Floating-point quaternion operations (addition, multiplication,reciprocal, norm) are often implemented "by the book".

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion
Advanced Engineering Materials, EarlyView.This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.
