ffmpeg 등이 ARM용 NEON을 지원하는듯 하다.
The ARM® NEON™ general-purpose SIMD engine efficiently processes current and future multimedia formats, enhancing the user experience. NEON technology can accelerate multimedia and signal processing algorithms such as video encode/decode, 2D/3D graphics, gaming, audio 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. NEON technology is cleanly architected and works seamlessly with its own independent pipeline and register file. 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. [링크 : http://www.arm.com/products/processors/technologies/neon.php] |
