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).
Cyber-Physical Systems-on-Chip (CPSoC) are a new class of sensor-and actuator-rich multiprocessor system-onchips (MPSoCs) whose operations are monitored, coordinated, and controlled using a computing-communication-control (C3) centric core with additional on-chip and cross-layer sensing and actuation capabilities that enable self-awareness within the observe-decide-act (ODA) paradigm. In order to build, evaluate, and illustrate the effectiveness of various features of this new MPSoC paradigm in a fast and cost effective way, a rapid prototyping and emulation platform along with the tool chains is absolutely necessary. In this paper, we present a design library and an FPGA emulation and prototyping platform to build and investigate self-aware adaptive computing using CPSoC paradigm. Our example implementation of CPSoC prototyping using Xilinx FPGAs includes ring-oscillator (RO) based multipurpose sensors integrated with a sensor network-on-chip (sNoC) which in turn is interfaced either to a bus based shared memory architecture or to a communication and computation networkon-chip (cNoC) distributed fabric supporting several actuation mechanism in the software and hardware stack. We also briefly discuss few applications of the CPSoC design library and the platform.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
