高音质MP3播放器的设计

Design of MP3 Player in Sound High-fidelity

提出了一款基于SOC型单片机的MP3音乐播放器,详细论述了其硬件和软件结构的设计。该系统使用主控制器C8051F020单片机和解码芯片VS1003B实现了对存储介质SD卡中音频文件的解码。在显示设计方面,系统配备了NOKIA5110液晶来显示播放内容的相关信息。由于采用了专用的音频解码芯片,该系统能够流畅地播放多种格式的音频文件且音质效果很好。经过多次的软硬件测试,该系统表现出了稳定、实用的特征。

This paper described a type of MP3 player based on a SOC-type MCU and the design of its hardware and software in detail.The system realized the decoding of audio files existed in storage medium SD card by making use of a master-control unit called C8051F020 and encoder-decoder chip named as VS1003B.Owing to the application of dedicated audio decoder chip,the system performed well in the respect of playing different kinds of audio files and acoustic fidelity.Through a series of hardware and software testing,the system has the characteristics of stability and practicality.
