Abstract

Temperature has become an important issue in nowadays MPSoCs design due to the ever increasing power densities and huge energy consumption. This paper proposes a temperature-aware task mapping technique for energy optimization in systems with dynamic voltage selection capability. It evaluates the efficiency of this technique, based on the analysis of the factors that can influence the potential gains that can be expected from such a technique, compared to a task mapping approach that ignores temperature.
