An MDE Approach for Energy Consumption Estimation in MPSoC Design

Energy Consumption is a leading criterion to take into account in the design of multiprocessor systems on chip (MPSoC). In this paper, we present a solution to estimate the energy consumption early in MPSoC design in order to nd a good performance/energy trade-o in the design ow. This solution is based on the injection of consumption estimators between the hardware components during the co-simulation of a system at the CABA (Cycle Accurate Bit Accurate) level. These estimators are designed using a design framework and the corresponding SystemC code is automatically generated thanks to a model driven approach. Our solution oers an energy estimation framework without changing the IP(Intellectual Property)source codes, using standalone estimation modules, which allows their reuse. The accuracy of this approach is checked by integrating the consumption estimation in the simulation of signicant applications.
