3.3. Advanced SIMD and VFP Extensions

The 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.

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

Note

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 the Cortex-A7 MPCore Floating-Point Unit Technical Reference Manual and Cortex-A7 MPCore NEON Media Processing Engine Technical Reference Manual for implementation-specific information.
