| Abstract: | The reduced feature size of electronic systems and the demand for high performance lead to increased power densities and high chip temperatures, which in turn reduce the system reliability. Thermal-aware task allocation and scheduling algorithms are promising approaches to reduce the peak temperature of multi-core systems with real-time constraints. However, as long as the worst-case chip temperature is not incorporated into system analysis, no guarantees on the performance can be given. This paper explores thermal-aware task assignment strategies for real-time applications with non-deterministic workload that are running on a multi-core system. In particular, tasks are assigned to the multi-core system so that the worst-case chip temperature is minimized and all real-time deadlines are met. Each core has its own clock domain and the static assigned frequency corresponds to the minimum operation frequency such that no real-time deadline is missed. Finally, we show that the proposed temperature minimization problem can efficiently be solved by metaheuristics. |
