What is the Limit of Energy Saving by Dynamic Voltage Scaling?
Dynamic voltage scaling (DVS) is a technique that varies the supply voltage and clock frequency based on the computation load to provide desired performance with the minimal amount of energy consumption. It has been demonstrated as one of the most effective low power system design techniques, in particular for real time systems. Previously, there are works on both ends of the DVS systems: the ideal variable voltage system which can change its voltage with no physical constraints, and the multiple voltage system which has a number of discrete voltages available simultaneously. In this paper, we study the DVS systems between these two extreme cases. We consider systems that can vary the operating voltage dynamically under various real-life physical constraints. Based on the system’s different behavior during voltage transition, we define the feasible DVS system and the practical DVS system. We build mathematical model to analyze the potential of DVS on energy saving for these differe...
