Cyberphysical Systems: Workload Modeling and Design Optimization

by Radu Marculescu and Paul Bogdan

We live in a world in which computation, communication, and control are continuously and increasingly interwoven to produce functionally rich and energy-efficient cyberphysical systems. We understand a cyberphysical system (CPS) to mean a network of embedded computational devices and an associated set of wired or wireless networks that can monitor and control various physical processes that occur in the environment (e.g., a power grid, transportation and communication network, or network of medical devices). Although the focus of the embedded systems community is on building computational models for specific embedded applications, in the CPS area the goal is not only to establish a reliable communication infrastructure between such computational elements, but also to include time- and feedback-based control as intrinsic components of the programming model.
