3.1 NEON technology

ARM NEON technology is the implementation of the Advanced SIMD architecture extension. It is a 64 and 128-bit hybrid SIMD technology targeted at advanced media and signal processing applications and embedded processors.

NEON instructions are available in both ARM and Thumb code.

Note:

Not all ARM processors support NEON technology. In particular, there is no NEON support for architectures before ARMv7.

Note:

The NEON register bank is shared with the VFP register bank.
