Increasing the number of cores integrated in chip augments power densities and temperature as well can affect reliability and performance of multi-core System On Chips (SOCs). For embedded systems evolving in variable ambient temperature environments, power consumption can vary significantly which may cause a chip thermal runaway. In this paper we propose a temperature aware DVFS-DPM (Dynamic Voltage Frequency Scaling and Dynamic Power Management) algorithm for real time systems coupled with a workload balance technique between the cores to equilibrate temperature gradients. Simulation results show that our approach avoids the problem of thermal runaway and minimize the total number of thermal cycles undergone by the cores. 1
