Peak-Power Aware Life-Time Reliability Improvement in Fault-Tolerant Mixed-Criticality Systems

Mixed-Criticality Systems (MCSs) include tasks with multiple levels of criticality and different modes operation. These systems bring benefits such as energy resource saving while ensuring safe However, management available resources in order to achieve high utilization, low power consumption, required reliability level is challenging MCSs. In many cases, there a trade-off between these goals. For instance, although using fault-tolerance techniques, replication, leads improving the timing reliability, it increases consumption can threaten life-time reliability. this work, we introduce an approach named Life-time Peak Power (LPP-MC) guarantee along peak reduction. This maps novel metric called Reliability-Power Metric (RPM). The LPP-MC uses balance processor cores improve chip. Moreover, MCSs, technique, task re-execution, utilized approach. We evaluate proposed by real avionics set, various synthetic sets. experimental results show that mitigates aging rate reduces up 20.6% 17.6%, respectively, compared state-of-the-art.
