Design methodology for battery powered embedded systems — In safety critical application

Battery powered embedded system can be considered as a power aware system for a safety critical application. There is a need of saving the battery power for such power aware system so that it can be used more efficiently, particularly in safety critical applications. Present paper describes power optimization procedure using real time scheduling technique having a specific dead line guided by the model based optimum current discharge profile of a battery. In any power aware system ‘energy optimization’ is one of the major issues for a faithful operation.
