NEON technology in nothing but an advance version of SIMD (single instruction multiple data ). 64-bit and 128-bit SIMD instructions are combined together to increase performance in standardized application of media and signal processing. NEON can execute MP3 audio decoding on CPUs running at 10 MHz and can run the GSM AMR (Adaptive Multi-Rate) speech codec at no more than 13 MHz. Different sized data type and operators such as 8-, 16-, 32- and 64-bit integer and single-precision (32-bit) floating-point data are supported by NEON technology. Those data and operations are very efficient to handle audio and video processing as well as graphics and gaming processing. The NEON hardware shares the same floating-point registers as used in Vector Floating Point. In NEON, the SIMD supports up to 16 operations at the same time.
