On the Equivalence of Idealised DVFS and Thermally Constrained DPM in Real-Time Systems
Ref: CISTER-TR-130801 Publication Date: 19 to 21, Aug, 2013Abstract:
Modern real-time embedded systems have increasingly penetrated our daily life and are also often constrained in terms of temperature and energy. In this paper, a thesis is defended that from real-time systems perspective, thermally constrained dynamic power management approaches behave very similar to idealised dynamic voltage and frequency scaling. Hence, existing dynamic voltage and frequency scaling solutions proposed for periodic/sporadic task models can be applied to thermally constrained dynamic power management systems with moderate effort. This work presents the similarities along with the distinctive elements between two approaches. Within the case study, the porting of a dynamic voltage and frequency scaling algorithm of the literature to thermally constrained dynamic power management system is demonstrated.
