3.4. Advanced SIMD and VFP Extensions

Advanced SIMD extension is a media and signal processing architecture that adds instructions targeted primarily at audio, video, 3-D graphics, image, and speech processing.

VFP extension performs single-precision and double-precision floating-point operations.


The Advanced SIMD architecture extension, its associated implementations, and supporting software, are commonly referred to as NEON.

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 Chapter 14 NEON and VFP Unit for implementation-specific information.
