Opportunities exist in systems that make choices among alternative devices on the basis of energy consumption (e.g., remote versus local computation, storage on flash versus disk). Finally, we introduce research efforts that focus on whole-system energy management.

Finally, we consider some challenges for application development and algorithm design specifically aimed at greater energy efficiency. The shaded portions of Fig. 6.1 show the new features covered in this chapter and provide context for the discussion.

Dynamic Voltage Scheduling (DVS),ing lies in using the slowdown to squeeze out processor idle cycles that might occur at the end of a task when it is run at the maximum processor speed, replacing those idle cycles with continuous processing at a lower speed and voltage level.

Introduction,enge in mobile computing and wireless communication. The limited availability of battery energy has emerged as a significant problem with the growth in reliance on mobile technology, the increased capabilities of the hardware, and the rising expectations of users for ubiquitous services.

Management of Device Power States,single device, exploiting the idle time offered by the access pattern for the device. We describe examples of policies that, given a workload, answer the questions of when to power down to a lower power state and when to power back up to a higher power state.
