In a comprehensive study using the Itsy pocket computer, the
authors measure both total system power and power dissipated
by individual subcircuits for represenative workloads. The results
suggest possible low-power design optimizations and power management

About the authors:
Marc A. Viredaz is a researcher at Hewlett-Packard Laboratories,
with interests in handheld and mobile computing, hardware
design, low-power systems and computer architecture. Marc
received his PhD from the Swiss Federal Institute of Technology
at Lausanne. He joined DEC's Western Research Laboratory (WRL)
in October 1995, where he became one of the hardware designers
of the Itsy pocket computer. DEC became part Compaq in 1998
and Compaq merged with HP
in 2002. Marc is now part of the Mobile and Media Systems
Lab, working on alternate ways of using handheld devices.
Deborah A. Wallach, formerly of HP
Labs, is currently at Google's System Laboratory. After receiving
her PhD from the Massachusetts Institute of Technology, she
joined the Western Research Laboratory (WRL) of Digital Equipment
Corporation, which later became part of Hewlett-Packard Labs.
She was a key system software builder for the Itsy pocket
computer. Her research interests include reducing energy consumption,
operating systems, networks and mobile computing.
