ABSTRACT
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).
Keywords: Cyber physical systems, Cross-layer approach,
Self-aware computing, Adaptive computing , MPSoC, CyberPhysical-System-On-Chip (CPSoC).
