Design And Implementation Of Media Player Based On ARM11

With the rapid development of media technology, manipulation and integrity become people pay more attention to be compact multimedia technology. Meanwhile, with the development of embedded systems in the worldwide popularity of continuous improvement and it became intelligent terminal product design preference. It known for its high-performance, single-chip, low-power consumption control, as well as feature upgrades and future expansion provides a great convenience. Embedded systems will be completely broken the traditional multi-chip architecture Multimedia player. Embedded systems will be completely broken the traditional multi-chip architecture Multimedia player. In this article, we completed a media player in the design process, through a combination of embedded systems, graphical interface programming technology, touch-screen technology combined approach.In this paper, we study, research status, research and innovation objectives first described the background and significance. We then introduce the ARM11 processor and embedded systems, including ARM11 processor, and its business model, embedded system and its development process and the basic concepts of embedded Linux. System functional requirements analysis, we give the overall framework for the design and discusses the detailed system development platform construction. Then, the system is on this basis, then, we describe a touch screen Multimedia player, including the introduction of a touch-screen technology, media player Mplayer transplant, as well as in the whole process of the player application to write design and implementation methods. Finally, the player’s performance is tested, play video files. We have introduced a graphical interface development environment for the establishment process, including the introduction of portable graphical user interface, Qt programming software, and the root file system is installed and the related configuration. In this paper we designed a sophisticated system has good flexibility and portability, using the ARM11 chip( Samsung S3C6410), for the main processor for embedded core board as the target platform, the establishment of multi-platform compatibility and embedded Linux operating system, built-in graphical programming software for embedded media player as a development environment, the application of open source embedded media player playback software Mplayer, QProcess the core application.In the end of this article, we summarize the design of the player, pointed out the problems and improved methods for guiding future designs...
