摘要
MP3是诸如音乐播放器,移动电话等移动设备上最为流行的高质量音频压缩格式。描述了在SoC芯片AS3310D上,基于通用软件优化技术和芯片上特有的DMA控制器,对MP3软件解码器的优化,最终获得了42.7%性能的提高和38.8%存储空间的节省。
MPEG-1 layer 3 is the most popular format for high quality compressedaudio in portable devices such as audio players and mobile phones. This paper proposes software optimization of MP3 decoder on SoC AS3310D based on general software optimization techniques and build-in DMA hardware controller, and the performance increase of 46.7 % and memory space decrease of 38.8 % over the original decoding software have been achieved.
