9:00 am—10:30 am

Opening Remarks, Awards, and Keynote Keynote Address: Design of Wireless Systems-on-a-Chip Bob Brodersen, Berkeley Wireless Research Center, University of California, Berkeley As the density of integrated circuit technology continues to improve exponentially, the amount of functionality that can be put on a chip continues to grow to the point now where a chip can include analog baseband and RF circuits, baseband digital processing, and processors for the network layer. This type of implementation requires optimization which covers the system specification and algorithms, processing architectures, and analog circuits. An approach which accomplishes this task will be described, as well as metrics which must be evaluated to make the critical, system level tradeoffs. The goal is to provide system level designers with the tools and feedback so they can be in control of the Systems-on-a-Chip design process.

Panel: How Should We Evaluate Systems Contributions to Ubicomp? Panelists: Keith Edwards, Palo Alto Research Center Armando Fox, Stanford University (moderator) Anthony LaMarca, Intel Research Brian Noble, University of Michigan Yi-Min Wang, Microsoft Research Because ubicomp systems always have a human in the loop, some of the traditional criteria by which classical systems work has been evaluated are not easily applied to ubicomp. This panel will take a hard look at evaluation criteria, including metrics, tactics, and possible new collaborations. Our panelists are academic researchers and industry practitioners who have architected, designed, implemented, and deployed mobile or ubiquitous computing systems to actual users. Look over the full description of the panel session, including bios of all the panelists.
