本文研究了热感知实时系统的可调度性分析。热约束在新一代微型嵌入式系统中变得越来越重要，例如医疗植入物。作为这项工作的一部分，我们将 [1] 中提出的用于能量收集系统的 PFPasap 算法改编为热感知系统。我们证明了其对于非具体固定优先级任务集的最优性，并提出了基于最坏情况响应时间上限的响应时间分析。我们通过对随机生成的任务系统进行广泛的模拟来评估所提出的界限的有效性。
This paper investigates schedulability analysis for thermal-aware real-time systems. Thermal constraints are becoming more and more critical in new generation miniaturized embedded systems, e.g. Medicals implants. As part of this work, we adapt the PFPasap algorithm proposed in [1] for energy-harvesting systems to thermal-aware ones. We prove its optimality for non-concrete1 fixed-priority task sets and propose a response-time analysis based on worst-case response-time upper bounds. We evaluate the efficacy of the proposed bounds via extensive simulation over randomly-generated task systems.
