Energy optimization of embedded software is of primary importance. Nevertheless, there is lack of accurate and usable methodologies and tools to estimate software performance (execution time, energy) and to allow a significant exploration of design alternatives. Current approaches use either instruction-level simulation (accurate but slow), or static-time source characterization (flexible but data-independent)...
Embedded operating systems (EOS) manage the resources of the system and control device operations, and play an important role on optimizing system energy consumption. This paper proposes a new approach to estimate and optimize the energy consumption of the EOS and the applications at a fine-grained level. The approach is based on a micro-architectural power model and a new estimation model for operating...
