Preemption managing method for real time operating system, involves interrupting execution of current task after calculated time interval for permitting current task and high priority task to be executed before end of execution delay

摘要

The method involves interrupting an execution of a current task from three tasks (T1-T3) after a calculated time interval for permitting the current task and the high priority task (T1) to be executed before an end of an execution delay, where the current and high priority tasks are assigned when a request of execution of the high priority task has the higher priority than the current task. The time interval is calculated for each task in a fixed manner, taking into account the execution of other tasks having the higher priority.
