摘要
时下,随着科技的不断发展和创新,嵌入式领域也得到了飞速的进步,而消费者日益增长的消费需求也刺激着嵌入式技术的不断前进。消费者的主要对象为电子与多媒体结合的产品,多媒体部件逐渐成为嵌入式产品中重要组成部分。所以,嵌入式技术与多媒体产品的相互融合显得尤为重要,并结方便消费者操作的图形界面将越来越广泛的应用到个人消费类电子产品的设计开发中。基于以上背景,本文研究并实现了基于嵌入式操作系统的MP3播放器。本次设计开发了一种应用于Linux系统的音乐播放器。该播放器基于QT技术和 Linux 操作系统, 利用 GNU 开发工具进行软件开发, 使用 C99标准的 C 硬件平台。介绍了MP3播放器的软硬件开发平台。细致分析了软件开发平台的建立,展示出了MP3播放器各功能实现的详细设计开发步骤,所计的MP3播放器能够支持优盘、SD卡等外接移动存储设备并支持完善的调节音量、上一曲、下一曲、快进快退、播放暂停、显示播放进度等条等功能。简述了MP3播放器的开发过程、ARM的硬件组成,Linux 操作系统的安装和使用程序移植的的方法,进而成功实现了该播放器的开发和最后的在硬件环境下的使用。

Abstract
Nowadays,with the continuous development of science and technology and innovation , the embedded field has also been a rapid progress , the increasing consumer spending also stimulates demand for embedded technology continues to advance .The main object of consumers for bination of electronic and multimedia products, ponents has gradually e an important part of embedded products . Therefore , embedded technology and multimedia products merging is particularly important, and easy to knot the consumer - to-use graphical interface will be more widely used in personal consumer electronics product design and development . Based on the above background , this paper embedded operating system - based MP3 player .Developed in this paper applied to the Linux system music player . The player based on the QT and Linux operating systems , GNU development tools for software development , using the C99 standard C language and can run on ARM920T hardware platform . MP3 player hardware and software development platform . Detailed analysis of the establishment of a software development platform , demonstrating the MP3 player to achieve the detailed design development steps , the MP3 player can support USB flash drives ,SD card and an external removable storage devices and supports perfect to adjust the volume on the track , ne
