摘要: 结合当前流行的uC/OS-Ⅱ v2.52对任务的管理形式,推导出了几种可用任务数扩充方案。给出了一个在ARM核MCU上运行效率较优的最小系统实例。在ARM7 MCU LPC2294上对改进后的操作系统进行资源消耗分析实验,得出时钟周期消耗数据,验证了该方案是一种比较理想的解决方案。

Abstract: Based on the uC/OS-Ⅱ v2.52 which is task management system, this paper presents solutions for increasing the number of usable tasks. An example of the least RTOS is given under the ARM MCU. Through the clock cycles from an experiment under the ARM7 MCU LPC2294, the solution is confirmed feasible.

Key words: RTOS, uC/OS-Ⅱ, expansion task, LPC2294, ARM
