【摘要】Embedded operating system is applied in many fields. Because embedded real-time operating system supports multiple tasks, it makes the program development easier, stabler and more reliable. Because of that, it becomes an important part of the embedded system. The paper introduces four kinds of embedded real-time operating systems, I. E. VxWorks, μClinux, μC/OS-II and Windows CE. Task scheduling in switching is analyzed and compared.%嵌入式操作系统在很多领域得到应用.由于嵌入式实时操作系统支持多任务,使得程序开发更加容易,在便于维护的同时还能提高系统的稳定性和可靠性,所以逐步成为嵌入式系统的重要组成部分.本文介绍4种嵌入式实时操作系统VxWorks、μClinux、μC/OS-Ⅱ和Windows CE,对多任务的调度切换进行了分析比较. 【总页数】4页(10-12,16)
