A Framework for Energy and Transient Power Reduction during Behavioral Synthesis
Abstract-- In battery driven portable applications, the minimization of energy, average power, peak power, and peak power differential are equally important to improve reliability and efficiency. The peak power and the peak power differential drive the transient characteristics of a CMOS circuit. In this paper, we propose a framework for simultaneous reduction of the energy and transient power during behavioral synthesis. A new metric called "Cycle Power Function" (CPF) is defined which captures the transient power characteristics as an equally weighted sum of the normalized mean cycle power and the normalized mean cycle differential power. Minimizing CPF using multiple supply voltages and dynamic frequency clocking under resource constraints results in the reduction of both energy and transient power. The cycle differential power can be modeled either as the absolute deviation from the average power or as the cycle-to-cycle power gradient. Based on the above, we develop a ne...
