摘要
本文深入分析了嵌入式实时操作系统内核Nucleus PLUS的可移植性,详细阐述了Nucleus PLUS在i.MX21处理器上的移植过程,重点介绍了目标硬件平台和内核定时器模块的初始化、内核中断响应和上下文保护的处理内容和流程,并通过测试例程验证了移植代码的正确性。
The portahility of Nucleus PLUS is deeply analyzed in this paper. And we specify the porting process of Nucleus PLUS for i.MX21 processor, in which the initialization of the target platform and the kernel timing module, the response of the kernel interrup- tion, and the process of the context protection are chiefly discussed. Finally, a verification of the porting is presented in the end.
