Computer method and apparatus for periodic scheduling with jitter-approximation tradeoff |
摘要 |
A method and apparatus of scheduling jobs each having respective (i) length of execution time and (ii) requested frequency of occurrence includes for each given job, allocation of a respective set of start times in a cycle in a manner that evenly spreads the given jobs over the cycle. Idle time slots are added or padded into the cycle in a manner which reduces jitter (i.e., the differences in spacing between consecutive occurrences of the same job). The method and apparatus enable a balance between period approximation and jitter reduction to be optimally achieved.
