基于ARM-Linux嵌入式播放器设计与实现

ped and widely used. Therefore, this paper proposes a solution for designing and implementing a player based on embedded ARM-Linux. The paper first analyzes the ARM architecture in detail and studies the porting technology of the embedded Linux operating system on the ARM9 microprocessor. This includes the establishment of a cross-compilation environment, application of boot loaders, porting of the embedded Linux kernel, and establishment of a root file system. Furthermore, the paper successfully achieves the porting of embedded Linux to the S3C2410 development board. Due to the hardware limitations of embedded systems, the commonly used graphical user interface (GUI) systems for PC are not suitable to run on them. Therefore, this paper chooses Minigui as the research object and successfully ports it to the S3C2410 development board after studying its architecture and related aspects. This enables the system to have a well-designed operating interface. For the player, this paper achieves the porting of Mplayer, a universal media player under Linux, to the S3C2410 development board. Through the study of audio data output, the problem of abnormal sound playback in Mplayer is solved. This results in the implementation of an embedded multimedia player system that combines music and video playback. Finally, the paper summarizes the work done and points out the issues that need to be further addressed and improved in embedded players.
