Feedback Thermal Control of Real-Time Systems on Multicore Processors

Real-time systems face significant challenges in thermal management with their adoption of modern multicore processors. While earlier research on feedback thermal control has shown promise in dealing with the uncertainties in the thermal characteristics, multicore processors introduce new challenges that cannot be handled by previous solutions designed for single-core processors. Multicore processors require the temperatures and real-time performance of multiple cores to be controlled simultaneously, leading to Multi-Input-Multi-Output (MIMO) control problems with inter-core thermal coupling.
