摘要

微处理器在便携式电子设备中消耗的能量中占很大一部分。动态电压缩放(DVS)允许设备在运行时通过降低处理器速度来降低能耗，从而相应降低处理器电压和能量。电压调度器通过分析应用约束和要求来确定适当的工作电压。一个完整的软件实现，包括应用程序和底层操作系统，表明分布式交换机在不需要大量软件修改的情况下有效地降低了能耗。

Voltage scheduling in the IpARM microprocessor system

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.
