摘要
在分析现有调度机制的基础上,提出了一种新的调度算法.该算法是一种混合型的优先级实时调度算法,由静态优先级、动态子优先级2部分组成,综合了固定优先级调度算法和动态优先级调度算法的优点,既可提高系统满足多任务时限的能力,又能解决优先级反转问题,从而提高了UC/OS-Ⅱ的实时性.
After status quo of existing scheduling mechanism analyzed, a new scheduling mechanism is put forward. It is a hybrid priorities real time scheduling algorithm which consists of two parts, the first is done statically and the second part is the assignment of the dynamic priority. By synthesizing the two algorithms, the deadline of tasks is satisfied and the priority reversal is also avoided.
