Sensor Network on Chip: A HW-SW Collaborated Method for Resilient MPSoC


Multiprocessor system-on-chip (MPSoC) is an attractive platform for embedded applications with growing complexity, because integrating a system or a complex subsystem on a single chip provides better performance and energy efficiency and lower cost per function. As feature sizes and power supply voltages continually decrease, MPSoC is becoming more susceptible to various transient threats, such as soft error and power/ground noise. Traditional solutions introduce large area, power and performance overheads to MPSoC. As the scale and complexity of MPSoC continuously increase, a systematic approach that not only detects reliability threats but also mitigates such threats accordingly at run time could potentially offer better performance, scalability, and flexibility for MPSoC designs. This talk will present a systematic approach, sensor network on chip (SENoC), to collaboratively detect, report, and alleviate run-time transient threats in MPSoC. SENoC not only detects threats and shares related information among processing units, but also plans and coordinates the related reactions. To highlight the details of our idea, SENoC is used and explained in case studies.


Jiang Xu received his Ph.D. degree from Princeton University in 2007. From 2001 to 2002, he worked at Bell Labs, NJ, as a Research Associate. He was a Research Associate at NEC Laboratories America, NJ, from 2003 to 2005. He joined a startup company, Sandbridge Technologies, NY, from 2005 to 2007 and developed and implemented two generations of NoC-based ultra-low power multiprocessor systems-on-chip for mobile platforms. Dr. Xu is an Associate Professor at Hong Kong University of Science and Technology. He is the founding director of Xilinx-HKUST Joint Lab and establishes Mobile Computing System Lab. He currently serves as the Area Editor of NoC, SoC, and GPU for ACM Transactions on Embedded Computing Systems and Associate Editor for IEEE Transaction on Very Large Scale Integration Systems. He is an ACM Distinguished Speaker and a Distinguished Visitor of IEEE Computer Society. He served on the steering committees, organizing committees and technical program committees of many international conferences. Dr. Xu authored and coauthored more than 70 book chapters and papers in peer-reviewed journals and international conferences. His research areas include network-on-chip, multiprocessor system-on-chip, optical interconnects, embedded system, computer architecture, low-power VLSI design, and HW/SW codesign.
