Abstract:

The solutions for porting programs from single-address space operating system to multiple-address space operating system were illustrated and contrasted in the architecture of embedded MIPS. Then a solution named "single device, multiple modules and architecture porting" was introduced to the program porting from Nucleus to Linux. Experiment results show that this solution is executable, low costing and effective.

Key words: single address space, multiple address space, Nucleus, Linux, porting

摘要：

以嵌入式环境中,MIPS架构下,程序从Nucleus到Linux操作系统的移植为例,探讨了从单一地址空间操作系统到多地址空间操作系统的程序移植方案,对多种方案进行了比较择优,提出了单一设备、多个模块、架构整体搬迁的移植方案。从移植的结果来看,方案可行、廉价、高效。
