为了支持面向能耗优化的容错实时任务调度算法研究,提出一种频率相关的时间Petri网—FRTPN.FRTPN引入用于动态电压调整的变迁频率设置空间以及和频率相关的静态引发时域,以支持调度算法的能耗评估及优化;同时它增加一类抑制弧刻画容错故障恢复过程.通过对基于检查点的容错实时能耗优化任务调度进行建模证明了FRTPN的有效性.
In order to support the research of fault-tolerant real-time task scheduling algorithm for power optimization, a frequency-dependent timed Petri net -FRTPN is proposed.FRTPN introduces variable frequency setting space for dynamic voltage regulation and frequency-dependent static triggering time domain to support Scheduling algorithm to evaluate and optimize the energy consumption.At the same time, it adds a class of anti-arc fault tolerance fault recovery process.Finally, the validity of the FRTPN is proved by modeling the fault-tolerant real-time energy consumption optimization task scheduling based on checkpoint.
