嵌入式系统的应用领域近年来在广度和深度飞速发展,基于平台化的嵌入式系统开发方式是必然趋势。本文通过在32位微控制器MC68331上移植μC/OS-II操作系统、构建一个嵌入式系统开发平台从而实现了嵌入式系统开发的平台化,详细论述了整个移植过程和在移植过程中涉及的基本问题,以及由MC68331处理器硬件特性所带来的移植问题并给出了详实的解决方案。该平台经测试后用于实际项目开发,大幅减少了开发时间和费用、证明了平台化开发方法的有效性。
In recent years, the application fields of embedded systems have been developing rapidly in breadth and depth. The development of embedded system based on platform is an inevitable trend. In this paper, we transplant the μC / OS-II operating system on the 32-bit microcontroller MC68331 and build an embedded system development platform so as to realize the platform development of embedded system. We elaborate on the whole migration process and the issues involved in the migration process Basic problems, as well as by the MC68331 processor hardware features brought by the transplant and gives a detailed solution. The platform has been tested for actual project development, drastically reducing development time and expense, and demonstrating the effectiveness of the platform development approach.
