3.2.1. NEON C extensions

The NEON C extensions are a set of new data types and intrinsic functions defined by ARM to enable access to the NEON unit from C. Most of the vector functions map directly to vector instructions available in the NEON unit and are compiled inline by the NEON enhanced ARM C compiler. With these extensions, performance can be achieved at the C level that is comparable to that obtained with assembly language coding.

See Appendix E Using NEON Support in the Compiler Reference Guide for more information.
