基于S3C2410的嵌入式多通道MP3的研究与设计

Research and Design of Multi-Channels of Embedded MP3 Player Based on S3C2410

针对现有MP3播放器功能的不足,采用三星公司的S3C2410芯片为核心处理器,以嵌入式ARM-Linux操作系统为平台,构建多通道MP3系统。并在对系统总体分析的基础上,进行硬件框图设计、音频解码电路设计、体系结构设计、软件驱动设计。根据S3C2410的DSP核和CD4066转换开关设计多通道切换,用类图进行说明MP3播放器的功能关系。

This paper aims at improving the disadvantage of current MP3 Player,uses SAMSUNG Company＇s S3C2410 chip as the core processor,embedded ARM-Linux operating system as the platform,construction of multi-channels MP3 System.And making Hardware diagram design,audio decoding circuit design,architecture design,software-driven design based on the general analysis.Designs the switch of Multi-Channels based on S3C2410 DSP core and CD4066 changeover.
