Dynamic power management is a design methodology aiming at controlling
performance and power levels of digital circuits and systems, with the
goal of extending the autonomous operation time of battery-powered
systems, providing graceful performance degradation when supply energy
is limited, and adapting power dissipation to satisfy environmental
constraints.
Dynamic Power Management: Design Techniques and CAD Tools addresses
design techniques and computer-aided design solutions for power
management. Different approaches are presented and organized in an order
related to their applicability to control-units, macro-blocks, digital
circuits and electronic systems, respectively. All approaches are based
on the principle of exploiting idleness of circuits, systems, or
portions thereof. They involve both the detection of idleness conditions
and the freezing of power-consuming activities in the idle components.
The book also describes some approaches to system-level power
management, including Microsoft's OnNow architecture and the `Advanced
Configuration and Power Management' standard proposed by Intel,
Microsoft and Toshiba. These approaches migrate power management to the
software layer running on hardware platforms, thus providing a flexible
and self-configurable solution to adapting the power/performance
tradeoff to the needs of mobile (and fixed) computing and
communication.
Dynamic Power Management: Design Techniques and CAD Tools is of
interest to researchers and developers of computer-aided design tools
for integrated circuits and systems, as well as to system designers.
