ARM NEONTM technology is a 128 bit SIMD (Single Instruction, Multiple Data) architecture extension for the ARM CortexTM-A series processors, designed to provide flexible and powerful acceleration for intensive multimedia applications, thereby delivering a significantly enhanced user experience. NEON technology accelerates multimedia and signal processing algorithms such as video encode/decode, 2D/3D graphics, audio, voice and speech processing, image processing, telephony, and sound synthesis by at least 3x the performance of ARMv5 and at least 2x the performance of ARMv6 SIMD.
The architecture is optimally defined and works seamlessly with its own independent pipeline and register file. The ARM Cortex-A8 processor with NEON technology is becoming widely accepted as the leading processor in multimedia applications ranging from smartphones and mobile computing devices to HDTV. NEON Features and Benefits NEON technology features a number of elements to increase performance and simplify software development, such as aligned and unaligned data access, support for integer and floating point data types, tight coupling to the ARM core, and a large register file with multiple views. Aligned and unaligned data access allows for efficient vectorization of SIMD operations. Support for both integer and floating point operations ensures adaptability to a broad range of applications, from compression decoding to 3D graphics. Tight coupling to the ARM core 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 multiple views enables efficient handling of data and minimizes access to memory, enhancing data throughput performance.
