School of Electrical, Electronic & Computer Engineering Stochastic Modeling Of Dynamic Power Management Policies And Analysis Of Their Power-Latency Tradeoffs

Dynamic Power Management (DPM) is one of the main system level low power technologies for Systems On Chip (SOCs). This paper presents a series of Markov models for various DPM policies and provides accurate analysis about their power and latency performances with full consideration of the shutdown and wakeup processes. The new models make it possible to incorporate latency analysis in terms of deadline satisfaction.
