| 摘 要： | 分析了某型寻北仪系统的硬件特点及相应的软件要求,限于寻北仪的单任务操作系统,需要一种任务调度策略来实现多任务实时性.基于此,对常规的RM调度和EDF调度策略进行了分析研究,设计实现了一种在寻北仪的单任务弱实时操作系统下,可以进行多任务动态实时调度的策略.该策略结合RM和EDF两种方法的特点,既考虑到任务的频度,又兼顾任...

| Abstract: | In this paper,the characteristics of the system software and hardware in a north seeker are analyzed.According to the system hardware and its single task OS environment,a special task scheduling technique should be adopted to meet the high real time request.Based on the common RM and EDF methods,a dynamic task scheduling method is designed and realized in this system,which combines the merits of the RM and EDF.This task scheduling method considers the urgency of system tasks and also take the frequency of s... |
