Microprocessors represent a significant portion of the energy consumed in portable electronic devices. Dynamic Voltage Scaling (DVS) allows a device to reduce energy consumption by lowering its processor speed at run-time, allowing a corresponding reduction in processor voltage and energy. A voltage scheduler determines the appropriate operating voltage by analyzing application constraints and requirements. A complete software implementation, including both applications and the underlying operating system, shows that DVS is effective at reducing the energy consumed without requiring extensive software modification.
