Abstract:

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.

Key words: power management, sleep, wake up, embedded systems
