2.6 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.


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


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