This tutorial surveys design methods for energy-efficient system-level design. We consider
electronic sytems consisting of a hardware platform and software layers. We consider the …

A unique feature of this open access textbook is to provide a comprehensive introduction to
the fundamental knowledge in embedded systems, with applications in cyber-physical …

Dynamic power management (DPM) is a design methodology for dynamically reconfiguring
systems to provide the requested services and performance levels with a minimum number …

Energy costs for data centers continue to rise, already exceeding $15 billion yearly. Sadly
much of this power is wasted. Servers are only busy 10--30% of the time on average, but …

This paper evaluates five policies for cluster-wide power management in server farms. The
policies employ various combinations of dynamic voltage scaling and node vary-on/vary-off …

There is great potential for boosting the performance of mobile devices by offloading
computation-intensive parts of mobile applications to the cloud. The full realization of this …

Accurate power characterization is important in computing platforms for several reasons
ranging from poweraware adaptation to power provisioning. Power characterization is …

A large portion of the power budget in server environments goes into the I/O subsystem-the
disk array in particular. Traditional approaches to disk power management involve …

In this paper we study four approaches to conserving disk energy in high-performance
network servers. The first approach is to leverage the extensive work on laptop disks and …
