Energy proportional management of residential gateways

We are presenting a novel methodology for energy proportional management of electronic devices on the example of a triple-play broadband residential gateway. Using the newly developed formal abstraction of hardware and software, combined with the associated design tools, it was possible to automate the generation of the energy management software and meet the regulatory energy requirements. The resulting energy savings amounted to 31%, 38% and 71% in the active, idle and sleep modes, respectively. Based on the expected 2014 worldwide gateway production, the achieved savings are predicted to reach half of the annual output of a 500MW coal-fired power plant.
