摘要
根据硬件提供的功耗管理机制,参考Intel和Microsoft公司制订的高级电源管理规范,在嵌入式领域中提出了系统工作的常规模式、空闲模式、休眠模式和睡眠模式四种功耗模式,并在嵌入式操作系统中使用电源管理模块,提供了有效的功耗管理机制。分析了基于操作系统功耗管理机制的功耗管理策略,从而实现系统的低功耗目的。
According to the APM specification, four types of power modes: Normal, Idle, Doze and Sleep based on the energy consumption management mechanism supported by hardware are presented. An energy consumption management module in embedded operating system to provide effective energy consumption management policies for application is also given. This paper also analyzes the energy consumption management strategies based on the energy consumption management policies of operating system to reduce the power consumption of system.
