基于S3C6410的嵌入式系统休眠与唤醒策略设计与实现

Design and implementation of system sleep and wake-up for embedded system based on S3C6410

系统休眠与唤醒作为电源管理的关键技术之一,实现了处理器功耗模式的切换和设备电源管理的间接管理。根据S3C6410处理器模块的特性和Windows Embedded CE 6.0电源管理驱动结构,研究并实现了嵌入式系统休眠与唤醒;同时,还对唤醒源设置这样的关键问题进行了研究,最后对该休眠与唤醒策略进行了功能验证和性能分析。实验结果表明,本设计具有良好的稳定性和有效性。通过对休眠唤醒在系统的电源管理过程中发挥的作用进行了定量分析,不失一般性,本设计可为其他嵌入式系统功耗控制提供参考解决方案。

As one of the key technologies of power management, system sleep and wake-up realizes processor power mode switching and indirect device power management. The paper studies and realizes the sleep and wake-up strategy based on S3C6410 and Windows Embedded CE 6.0 driver structure for an embedded system. Besides, many key issues, such as how to set up the wake-up source, are analyzed. At last, the functional verification and performance analysis are carried out. Experimental results exhibit that our solution has high reusability and high stability. Without loss of generality, the proposed method can be referenced for other embedded system as a power control solution.
