嵌入式实时操作系统的移植裁剪技术分析

Analysis of Cuting and Transplanting of Embedded Real-Time Operating System

当前的工程应用中，通过移植操作系统可提升微处理器的性能，然而操作系统的移植存在较为复杂的模块对接问题。针对μC／OS-Ⅱ实时操作系统移植过程中的三个关键问题：中断模块的移植、时钟系统模块的移植和内核的裁剪，提出了具体解决方案。实验结果表明提出的操作系统的内核移植裁剪方案具有低成本、易实现的特点。

The performance of the microprocessor can be promoted by transplanting the operating system （OS） in the engineering application, but the transplanting of the OS was a complicated procedure. Putting up with the solution to solve the three key problems in the procedure of transplanting about the μC/OS-Ⅱ real-time operat- ing system, namely, the transplanting of the interrupted model, the transplanting of the time system and the cut- ting of the kernel. The experimental results show that the proposed kernel transplanting scheme of the operating system has the characteristics of low cost and easy implementation.
