发布时间：2019-04-01 23:01
【摘要】：现有数码播放器一般采用DSP或MCU的架构,结构相对比较复杂,且不易升级和扩展功能。针对此问题,本文设计并实现了一种基于S3C6410芯片的嵌入式数码播放平台方案。 该方案采用硬件和嵌入式软件相结合的方式,硬件部分由嵌入式处理器核心电路和扩展电路部分组成。嵌入式处理器核心电路由三星公司的ARM11S3C6410芯片、1GB的NAND FLASH存储器和128MB的DDR存储器组成。扩展电路包括USB接口、串行接口、网络接口、音频电路、触摸屏电路和LCD视频处理电路等部分组成。软件部分选择Linux2.6.28作为嵌入式操作系统内核,而应用程序根据数码播放器的功能选用开源的音视频播放软件Mplayer。通过配置、编译等软件设计,解决了Linux操作系统在ARM11S3C6410处理器上的移植问题,在此基础上,通过移植根文件系统,完成了Linux软件平台的构建。最终,通过配置、编译和移植音视频播放软件Mplayer,完成了基于ARM嵌入式处理器的数码播放平台的开发。 硬件测试结果表明,该平台实现了数码播放的功能,相对于现行的数码播放器而言具有更好的功能扩展特性和便于升级的优势。这对未来多功能数码播放产品的研制具有重要的参考意义。
[Abstract]:Existing digital players generally use DSP or MCU architecture, the structure is relatively complex, and it is not easy to upgrade and expand functions. In order to solve this problem, an embedded digital playing platform based on S3C6410 chip is designed and implemented in this paper. The scheme adopts the combination of hardware and embedded software. The hardware part is composed of the core circuit of embedded processor and the extended circuit. The core circuit of embedded processor is composed of Samsung ARM11S3C6410 chip, 1GB NAND FLASH memory and 128MB DDR memory. The expansion circuit consists of USB interface, serial interface, network interface, audio circuit, touch screen circuit and LCD video processing circuit. In the software part, Linux2.6.28 is chosen as the kernel of the embedded operating system, while the application chooses the open source audio and video playback software Mplayer. according to the function of the digital player. The transplant problem of Linux operating system on ARM11S3C6410 processor is solved by software design such as configuration and compilation. On this basis, the construction of Linux software platform is completed by transplanting root file system. Finally, the development of digital playback platform based on ARM embedded processor is completed by configuring, compiling and porting audio and video playback software Mplayer,. The hardware test results show that the platform realizes the function of digital playback, and it has better function expansion characteristics and the advantage of easy to upgrade than the current digital player. This has important reference significance for the development of multi-functional digital playback products in the future.
