Number Formats, Error Mitigation, and Scope for 16‐Bit Arithmetics in Weather and Climate Modeling Analyzed With a Shallow Water Model

open access: yesJournal of Advances in Modeling Earth Systems, 2020
The need for high‐precision calculations with 64‐bit or 32‐bit floating‐point arithmetic for weather and climate models is questioned. Lower‐precision numbers can accelerate simulations and are increasingly supported by modern computing hardware.

Robustness Analysis of Floating-Point Programs by Self-Composition

open access: yesJournal of Applied Mathematics, 2014
Robustness is a key property for critical systems that run in uncertain environments, to ensure that small input perturbations can cause only small output changes.

Mixed abstractions for floating-point arithmetic [PDF]

open access: yes2009 Formal Methods in Computer-Aided Design, 2009
Floating-point arithmetic is essential for many embedded and safety-critical systems, such as in the avionics industry. Inaccuracies in floating-point calculations can cause subtle changes of the control flow, potentially leading to disastrous errors. In this paper, we present a simple and general, yet powerful framework for building abstractions from ...

Radix Conversion for IEEE754-2008 Mixed Radix Floating-Point Arithmetic [PDF]

open access: yes, 2013
Conversion between binary and decimal floating-point representations is ubiquitous. Floating-point radix conversion means converting both the exponent and the mantissa.

Fused floating-point arithmetic for DSP [PDF]

open access: yes2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008
This paper extends the consideration of fused floating-point arithmetic to operations that are frequently encountered in DSP. The fast Fourier transform is a case in point, it uses a complex butterfly operation. For a radix-2 implementation, the butterfly consists of a complex multiply followed by the complex addition and subtraction of the same pair ...
