NEON Enhancing User Experience
NEON enhances many multimedia user experiences:
Watch any video in any format
Edit and enhance captured videos - video stabilization
Anti-aliased rendering and compositing
Game processing
Process multi-megapixel photos quickly
Voice recognition
Powerful multichannel hi-fi audio processing
NEON Features and Benefits
NEON supports the widest range of multimedia codecs used for internet applications:
Many soft codec standards: MPEG-4, H.264, On2 VP6/7/8, Real, AVS
Ideal solution for normal size "internet streaming" decode of various formats
Not just for codecs - also applicable to 2D and 3D graphics and other vector processing
Off the shelf tools, OS support, and ecosystem support
Fewer cycles needed:
NEON will give 60-150% performance boost on complex video codecs
Individual simple DSP algorithms can show larger performance boost (4x-8x)
Processor can sleep sooner, resulting in overall dynamic power saving
NEON technology features a number of elements to increase performance and simplify software development, such as:
Aligned and unaligned data access allows for efficient vectorization of SIMD operations.
Clean instruction set architecture designed for autovectorizing compilers and hand coding.
Efficient access to packed arrays such as ARGB or xyz coordinates
Support for both integer and floating point operations ensures adaptability to a broad range of applications, from codecs to High Performance Computing to 3D graphics.
Tight coupling to the ARM processor provides a single instruction stream and a unified view of memory, presenting a single development platform target with a simpler tool flow.
The large NEON register file with its dual 128-bit/64-bit views enables efficient handling of data and minimizes access to memory, enhancing data throughput.
