Ne10 is a library of common, useful functions that have been heavily optimised for ARM-based CPUs equipped with NEON SIMD capabilities. It provides consistent, well-tested behaviour, allowing for painless integration into a wide variety of applications via static or dynamic linking.

The library provides some of the fastest open source implementations of key operations available for the ARM v7-A and v8-A architectures, particularly focusing on math, signal processing, image processing, and physics functions.
