| 摘 要： | OMAP芯片是TI公司推出的具有双核结构的微处理器，目前已经广泛地应用于无线通信领域。针对OMAP的结构特点，平台的ARM端运行Montavista Linux操作系统，主要进行无线网络通信和人机界面交互等任务；DsP端运行DSP／BIOS操作系统，用于音频编解码等实时数值运算。DSP端应用程序在RF6框架的基础上，着重对数据处理模块、底层驱动模块等进行了设计。该平台具有很好的扩展性，目前已经开发了MP3下载播放、IP电话用户终端等车载应用。

| Abstract: | OMAP,a two-core MPU made by TI Inc.has already been widely used in the area of wireless communication.Considering its unique structure,the Montavista Linux OS has been employed on the platform's ARM side,which mainly deals with wireless communication and human computer interface;on the DSP side,DSP/BIOS has been employed to do real-time computing like audio encoding and decoding.The application software on DSP side which is based on RF6 framework recommended by TI inc.includes design of data processing module,driver module,and so like.Such platform has displayed great expansibility,and now certain on-vehicle applications such as downloading and playing MP3 files,user terminal of IP phone have been completed. |
