The Advanced SIMD architecture extension is a media and signal processing architecture that adds instructions targeted primarily at audio, video, 3-D graphics, image, and speech processing.
The Advanced SIMD architecture extension, its associated implementations, and supporting software, are commonly referred to as NEON MPE.
NEON MPE includes both Advanced SIMD instructions and the ARM VFPv3 instructions. All Advanced SIMD instructions and VFP instructions are available in both ARM and Thumb states.
See the ARM Architecture Reference Manual for more information.
See the Cortex-A9 NEON Media Processing Engine Technical Reference Manual for implementation-specific information.
