Stochastic Rounding: Algorithms and Hardware Accelerator
Mantas Mikaitis
Algorithms and a hardware accelerator for performing stochastic rounding (SR) are presented. The main goal is to augment the ARM M4F based multi-core processor SpiNNaker2 with a mo…

Issues with rounding in the GCC implementation of the ISO 18037:2008 standard fixed-point arithmetic
Mantas Mikaitis
We describe various issues caused by the lack of round-to-nearest mode in the \textit{gcc} compiler implementation of the fixed-point arithmetic data types and operations. We demon…

Stochastic rounding and reduced-precision fixed-point arithmetic for solving neural ordinary differential equations
Michael Hopkins, Mantas Mikaitis, Dave R. Lester +1
Although double-precision floating-point arithmetic currently dominates high-performance computing, there is increasing interest in smaller and simpler arithmetic types. The main r…
