摘要
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。
With the rapid development of embedded system, its application domain are getting more and more broad and far-reaching, Thus platform based embedded developing system is the inevitable trend. This paper builds a practical development platform for embedded system by means of migrating μC/OS-Ⅱ operating system into the MC68331 MCU. We present the entire migrating process as well as the basic principle involved. Migrating obstacles caused by MC68331 hardware feature are discussed and the corresponding solutions are also given. Test on real project application show that this embedded platform can observably reduce developing time and expense, which proved its efficiency and effectiveness.
