Cyber–physical systems (CPSs) are physical and engineered systems whose operations are monitored, coordinated, controlled, and integrated by a computing, control, and communication core.We propose Cyberphysical-System-on-Chip (CPSoC), a new class of sensor and actuator-rich multiprocessor systemson- chip (MPSoCs), that augment MPSoCs with additional onchip and cross-layer sensing and actuation capabilities to enable self-awareness within the observe-decide-act (ODA) paradigm. Unlike traditional MPSoC designs, CPSoC differs primarily on the co-design of computing-communication-control (C3) systems that interacts with the physical environment in real-time in order to adapt system behavior so as to dynamically react to environmental changes while achieving overall design goals. We illustrate CPSoC’s potential through a virtual sensor network that accurately estimates run-time power for variability affected subsystems using noisy thermal sensors in improving system goals and Quality-of-Service (QoS).
