The design of cyber-physical systems (CPSs) faces various new challenges that are unheard of in the design of classical real-time systems. Power optimization is one of the major design goals that is witnessing such new challenges. The presence of interaction between the cyber and physical components of a CPS leads to dependence between the time delay of a computational task and the amount of workload...
In this paper, we propose to take the relationship between delay and workload into account in the optimization of cyber-physical systems (CPSs). Since the components at the physical side continuously change their values or properties, a longer delay at the cyber part may result in a bigger workload for the next computation. We formulate this tradeoff and apply it to the power optimization of CPS....
