Draft version Energy Estimation and Optimisation of Embedded Systems using Cycle Accurate Simulation

This paper presents a method for energy consumption estimation and optimisation on hardware-software embedded systems-on-chip using cycle-accurate simulation. Higher level energy estimations of SoC are proposed by some other approaches [2] [3] [4] [5]. Each one covers one stage on the highest levels of the design flow. However none enables to estimate and optimize the energy dissipation of all elements of an architectural description of an embedded system. A complete approach allowing this should a) use concurrent and very fast simulation, b) provide the energy dissipation of all the components including new accelerators and the interconnections with enough accuracy and c) give the energy dissipation evolution of the system to experiment dynamic low power techniques at system level. We present a new approach that, using some ideas from previous approaches
