Framework for Estimating Energy Consumption in Embedded Systems

Cyber-Physical Systems (CPS) are characterizedby an intensive interaction between its electro-mechanicaldevices and the embedded computer system. In most of thesesystems the battery autonomy is crucial, since power failurescan render the system inoperable. Therefore CPS designersmust take good-care regarding its energy consumption. Thispaper presents a framework to monitor the energy consump-tion in CPS in order to estimate its autonomy. The developedapproach is based on the characterization of the embeddedsoftware operating modes, which represent the operationalstates of the system. To illustrate the proposed framework we carried out a case-study applied to mobile robotics.
