Embedded Linux power management on the Intel Atom processor

A look at power management considerations and techniques when designing embedded Linux applications for the Intel Atom processor. Explains how product designers can enhance the power efficiency of their products by taking advantage of power management capabilities in MontaVista Linux and in the Intel Atom processor. Reviews best practices for using CPUfreq, the ondemand governor, and wakeup mitigation with PowerTOP. Topics also include an understanding of power balancing, Intel SpeedStep® Technology, c-states, and p-states, along with ways to make Linux device drivers aware of power management. (39 slides)
