对于实时计算系统，能量效率、服务质量和容错是主要的设计关注点。在这项工作中，我们研究的问题，可靠的和能源意识的固定优先级（m，k）的最后期限执行备用备用。备用备用系统采用主处理器和备用处理器来提供对永久性和瞬时性故障的容错。为了降低这类系统的能量消耗，我们提出了一种新的调度方案下的QoS约束的（m，k）期限。评估结果表明，我们提出的方法显着优于以前的研究，在节能，同时确保（m，k）-期限和容错的实时系统。
For real-time computing systems, energy efficiency, Quality of Service, and fault tolerance are among the major design concerns. In this work, we study the problem of reliable and energy-aware fixed-priority (m,k)-deadlines enforcement with standby-sparing. The standby-sparing systems adopt a primary processor and a spare processor to provide fault tolerance for both permanent and transient faults. In order to reduce energy consumption for such kind of systems, we proposed a novel scheduling scheme under the QoS constraint of (m,k)deadlines. The evaluation results demonstrate that our proposed approach significantly outperformed the previous research in energy conservation while assuring (m,k)-deadlines and fault tolerance for real-time systems.
