μC/OS-II系统在DM642平台的移植与音频模块开发
Porting μC/OS-II to DM642 DSP and audio module development
本文简要介绍了μC/OS-II操作系统并分析了TI公司DM642 DSP芯片的体系结构。结合两者的特点，本文较详细的描述了移植的准备工作、工具及步骤过程，分析了其中的重点和难点。编写了Boot代码及二进制文件转换代码，实现了通过外部FLASH二级引导程序完成上电自举过程。文章最后基于μC/OS-II任务实现了对DSP平台音频模块的配置，完成音频数据的采集和回放功能。
In this paper, μC/OS-II operating system and the architecture of TI DM642 DSP are introduced. This paper describes the preparation, tools and methods for porting and analyses the key points. The booting codes and binary file conversion codes are written to implement DM642 boot by the external FLASH memory. In addition, this paper carries out the configuration of the DSP audio module based on μC/OS-II task, and complete the capturing and playback of audio data.
