Towards Energy - Conscious Class Transformations for Data - Dominant Applications : a Case Study

embedded systems, the energy consumed by the data memory organisation represents a very large cost. We present a method to explore the design space of an object-oriented application in order to optimise the energy consumption and the footprint of the memory. Because we are working at the class design level, we can exploit the functionality of the system and focus on optimising the data related properties of the classes. We demonstrate our technique with a case study in which we achieve a gain of at least 35% in the energy cost factor.
