嵌入式操作系统Nucleus的移植研究

Porting Technology Research of Embedded Operating System

嵌入式系统作为计算机应用的一个崭新领域，以其简洁、高效等优点越来越多地受到人们的关注，而要开发一个嵌入式应用系统，则需要嵌入式硬件、嵌入式操作系统及相应的开发工具等。其中嵌入式操作系统是嵌入式应用系统中的基础部分，占有十分重要的地位，针对不同硬件平台。往往要进行嵌入式操作系统的移植。Nucleus是一种典型的嵌入式操作系统，具有体积小、功能强大、易于定制等特点，通过对Nucleus系统结构特点的分析，在基于SEP4020微处理器的评估板上，详细地论述了将嵌入式Nucleus操作系统移植到具体硬件平台上需要完成的工作。

The embedded system as a new field of computer applications, with its simple, efficient, and other advantages are increasingly of concern. And to develop an embedded application system requires embedded hardware, embedded operation system and the corresponding development tools. The embedded operation system is the base part of embedded system, opposing very important position, and would be ported to support a new hardware phfform. Nucleus is a typical embedded system that has many virtues such as light-weight, strong performance, easy to make, etc. Through the analysis of Nucleus system structure, with the target board based on SEP4020 microprocessor, it has discussed Nucleus embedded operating system will migrate to a specific hardware platform needs to be done in detail.
