NEON technology is a 128-bit SIMD (Single Instruction, Multiple Data) architecture extension for the ARM Cortex™-A series processors, designed to provide flexible and powerful acceleration for consumer multimedia applications, delivering a significantly enhanced user experience. It has 32 registers, 64-bits wide (dual view as 16 registers, 128-bits wide.
NEON instructions perform "Packed SIMD" processing:
- Registers are considered as vectors of elements of the same data type
- Data types can be: signed/unsigned 8-bit, 16-bit, 32-bit, 64-bit, single precision floating point
- Instructions perform the same operation in all lanes
The ARM Cortex™-A series processors with NEON technology, as well as ARM's Mali multimedia hardware solutions are used in multimedia applications ranging from smartphones and mobile computing devices to HDTV.
