Lesson 3: Adding Power Management Support to an OAL
As discussed in Chapter 3, "Performing System Programming," Windows Embedded CE 6.0 provides a comprehensive set of power management features based on a Power Manager component that OEM developers can customize to implement system power state definitions as appropriate for their hardware platforms. In relationship to the OAL, implementing power management capabilities is a twofold task. You need to enable the operating system to control the power state of the hardware components and you need to enable the hardware platform to inform the operating system about power state changes. Most embedded devices require at least basic power management support to reduce power consumption and prolong battery life.
After this lesson, you will be able to:
? Describe how to reduce processor power consumption.
? Identify the transition paths to suspend and resume the system.
Estimated lesson time: 15 minutes.
