The feasibility of integrating antennas and required circuits to form wireless interconnects in foundry digital CMOS technologies has been demonstrated. The key challenges including the effects of metal structures associated with integrated circuits, heat removal, packaging, and interaction of transmitted and received signals with nearby circuits appear to(More)
This is the second version of the technical report TR-LPH-2011-002. A summary of changes to the previous version is given below. • Section 3.3 has been updated with newer memory protection schemes, including mechanisms for stacked memory. • Section 4.2 has been added to include error detection techniques for intermittent timing errors. • Section 4.3.1 has(More)
The achievable signal-to-noise ratio for an 18-GHz wireless clock distribution system has been estimated by extrapolating from the current status of the clock receiver, the integrated antenna performance, and the understanding of noise sources and coupling mechanisms. It is estimated that a SNR of-23 dB is achievable at the input of the frequency divider(More)

This paper describes the system design developed for Team Gator Nation's submission to the 2007 DARPA Urban Challenge. In this event, vehicles had to navigate on city streets while obeying basic traffic laws. One of the major challenges was interacting with other vehicles such as at intersections. To address these challenges, a hybrid Toyota Highlander was(More)
Operating the Echelon system at optimal energy efficiency under a wide range of environmental conditions and operating scenarios requires a comprehensive and flexible resiliency solution. Our research is focused in on two main directions: providing mechanisms for proportional resiliency which use application-tunable hardware/software cooperative error(More)
This paper describes the system design developed for Team Gator Nation's submission to the 2007 DARPA Urban Challenge. A hybrid Toyota Highlander has been automated and instrumented with pose estimation (GPS and inertial) and object detection (vision and ladar) sensors. The control architecture consists of four primary Element implements the Adaptive(More)
