As technology edges closer to fundamental limits, variations of process parameters, operational voltage, and temperature (PVT variations) have to be accounted for. This paper proposes to make higher levels aware of these variations and bring them under system control by using software controlled body biasing. PVT variations can thus be exploited to reduce power and energy consumption.— Axel Jantsch, TU Wien
