Implement an MP3 audio decoder with the ARM Neon Multimedia.pdf

The ARM Cortex-A8 processor is the most advanced, high performance, low-power processor by ARM. Based on the ARMv7 architecture, the processor suits a variety of mobile and consumer applications, including mobile phones, STBs, game consoles and car navigation. As the core technology of Cortex-A8 processor, NEON technology has the flexibility to implement multiple combinations of video encode/decode, 3D graphics, speech processing, audio decoding, image processing and baseband processing. NEON technology is a 64,128bit single instruction multiple data stream (SIMD) instruction set. NEON supports 8-, 16-, 32-, 64bit integer and single precision floating- point SIMD operations to handle audio, video, image and other data processing. NEON technology has separate registers and pipeline, which is independent of the ARM integer pipeline. 출처 : http://www.embedded.com/222301334
