文档介绍：基于嵌入式ARM920T的视频播放器设计
摘要
嵌入式技术已经成为了后PC时代的核心技术,而基于嵌入式技术的便携式视频播放器由于体积小、重量轻、携带方便等特点,具有极广的市场前景,所以嵌入式视频播放器成为了现在IT行业研究的热点。本文提出了一种基于ARM9处理器,以嵌入式Linux为底层操作平台的嵌入式视频播放器的设计方案。
本文首先介绍了视频播放器软硬件的整体设计方案,然后详细介绍了如何通过移植Bootload、Linux内核和制作根文件系统来完成搭建视频播放器底层操作平台的工作,最后通过移植开源的多媒体播放器软件MPlayer和设计相关控件完成了整个视频播放器的设计工作。
最后,总结了论文所做的工作,指出了嵌入式播放器所需要进一步解决和完善的问题。

Design of Video Player Based on Embedded ARM920T
Abstract
Embedded technology has e the core technology of the post-PC era, and based on embedded technology of portable video player for small volume, light weight, convenient to carry have a very wide prospect of market, and so embedded video player to e a research focus of the IT industry. This paper puts forward a kind of embedded video player design scheme,the scheme is based on the ARM9 processor ,and the Embedded Linux as the underlying operating platform.
This paper first introduced the video player overall design scheme of software and hardware ,then detailed in detail how to transplant Bootloader, Linux kernel and make a root file system plete the work to build a video player underlying operating platform ,finally ,through transplantation of open source multimedia player software MPlayer and design controls plete the design work of the video player.
Finally, summarize the work of this paper, points out the embedded player which need to be solved and perfected problem.
Keywords: Embedded,Video player,Embedded Linux,ARM
