Dynamic voltage selection and adaptive body biasing have been shown to reduce dynamic and leakage power consumption effectively. In this chapter we present an energy optimization approach for time constrained applications implemented on multiprocessor systems. We start by introducing a genetic algorithm that performs the mapping and scheduling of the application on the target hardware architecture. Then, we discuss in detail several voltage selection algorithms, explicitly taking into account the transition overheads implied by changing voltage levels.
