Power consumption became one of the most critical limiting factors in modern electronics systems design from Internet of Things to high-performance computing systems as the device, and circuit techniques are being matured. By contrast, system-level low-power design avoids the inefficient use of devices and circuits by exploiting the application characteristics and user behaviors. As a result, it provides opportunities to further reduce the total system power consumption beyond the limit of the devices and circuits. Recently, it has been shown that low-power electronics design methodologies can also efficiently reduce power consumption of the physical world, that is, power-aware CPS (cyber-physical systems) design extends the scope of low-power design of electronics systems to physical worlds such as vehicle drivetrain, building HVAC (heat, ventilation and air conditioning), power grid (generation, transmission, and distribution), etc.

Introducing several breakthroughs in cross-layer low-power design that we have developed, this talk demonstrates how we extend the scope of system-level low-power design from embedded computing systems to CPS. In general, physical worlds’ power consumption is orders of magnitude higher than that of cyber worlds, and thus low-power CPS indeeds achieves holistic power saving. More specifically, we introduce our targets of low-power design ranging from CPU, memory and interconnects to energy harvesting, energy storage, electric vehicles, and drones. This talk will inspire the current and future low-power CPS with an emphasis on physical worlds within the framework of Design Automation of Things.
