Lesson Summary

Power management is an important Windows Embedded CE feature that ensures efficient power consumption on target devices. OEMs should implement power management features in the OAL to enable transitions from full-power mode to Idle and Suspend modes and Critical Off state for battery-powered devices. Implementing power management support involves re-synchronizing timer-related kernel variables, powering down peripherals, putting RAM into self-refresh mode, setting wakeup conditions, and suspending the CPU. It is not trivial to implement these low-level routines, yet Microsoft provides sufficient reference code in the sample BSPs to get a better understanding of the implementation details.
