Scheduling approach for non real-time applications in open real-time system based on two-level scheduling scheme
Wang Jian-guo · Journal of Computer Applications · 2008
In an open real-time system,the coexistence of different kinds of real-time and non real-time applications makes the system scheduling mechanism face new requirements and challenges.One scheduling mechanism of the open systems was introduced,and that the nonpreemptable sections may influence system schedulability in non real-time applications scheduling was pointed out.And then,a scheme which can remedy the limitations about the previous scheduling scheme was presented and the two-level scheduling scheme of open real-time system was improved.Ultimately,the schedulability of hard real-time applications,soft real-time applications and non real-time applications was guaranteed.
