文摘
- •
We adopt an effective power model to analyse energy consumption of processors in HCS.
- •
The presented fault model captures the case of task execution more precisely.
- •
We employ the share recovery technique to address the soft error during task scheduling.
- •
The slacks among the processors are reclaimed with system reliability preserving.
- •
Higher system reliability can be achieved even when soft faults are encountered.
