International audienceDesigning low power complex embedded systems is a main challenge for corporations in a large number of electronic domains. There are multiple motivations which lead designers to consider low power design such as increasing lifetime, improving battery longevity, limited battery capacity, and temperature constraints, etc. Unfortunately, there is a lack of efficient methodology and accurate tool to obtain power/energy estimation of a complete system at different abstraction levels. The Open People project addresses this topic and proposes a global framework for power/energy estimation and optimization of heterogeneous MultiProcessor System on Chip (MPSoC). Within this framework, a power modeling methodology is defined. Th...
