3.5 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 at C level can be comparable to performance obtained with assembly language coding.
