Systems and methods for assigning tasks to derived timers of various resolutions in real-time systems to maximize timer usage

摘要

One or more derived timers based on a source timer are provided to accommodate a plurality of periodic tasks while maintaining the high resolution of the source timer. To accommodate a number of periodic tasks, a number of derived timers can be selected utilizing a novel method based on the number of periodic tasks that are most time-critical, the number of tasks that are less time-critical, and the number of tasks that can be performed during the source timer interval. The interval and start time for each derived timer is selected based the source timer and number of the derived timer. After establishing the derived timers, the most time-critical tasks can be assigned to the source timer and the less time-critical tasks arranged amongst the derived timers.
