What’s Ne10?

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. The library currently focuses primarily around math, signal processing, image processing, and physics functions.

Building CircleCI

Out of the box, Ne10 supports the Linux, Android, and iOS platforms. For instructions on building Ne10 for these platforms, please consult the build instructions in It is possible to use the library on other platforms (or, indeed, “without a platform”), however you may have to fiddle with some of the build configuration files.

Once Ne10 has been built, it can be linked against just like any other C library. To link C code against Ne10, for instance, the compiler must first be aware of Ne10's library and header files — those within build/modules/ and inc/. To do this, these files can be copied to the standard directories used by compilation tools by running make install, or by installing Ne10 from a package manager. Following this, you can simply include Ne10.h in your C code, and ask the compiler to link against the NE10 library (e.g. with -lNE10).


Ne10’s official documentation is generated from doxygen annotations in the source code. As such, these documents can be generated locally from the codebase by running doxygen within the doc directory (producing results in doc/html), or viewed remotely as hosted copies available over the Internet.

We also have a handful of carefully prepared sample code snippets in the samples/ directory that outline how Ne10 can be used to accomplish a number of common tasks. These include example programs to perform the FFT, FIR, and matrix multiply operations.


Ne10 welcomes and encourages external contributions of any and all forms. If you’ve found a bug or have a suggestion, please don’t hesitate to detail these in the official issue tracker. For those looking to get their hands dirty and contribute code (the best kind of contribution!), please see for more details.
