    • Measuring Code Optimization Impact on Voltage Noise 

      Kanev, Svilen; Jones, Timothy M.; Wei, Gu-Yeon; Brooks, David M.; Janapa Reddi, Vijay (2013)
      In this paper, we characterize the impact of compiler optimizations on voltage noise. While intuition may suggest that the better processor utilization ensured by optimizing compilers results in a small amount of voltage ...
    • Voltage Noise in Production Processors 

      Janapa Reddi, Vijay; Kanev, Svilen; Kim, Wonyoung; Campanoni, Simone; Smith, Michael D.; Wei, Gu-Yeon; Brooks, David M. (Institute of Electrical & Electronics Engineers (IEEE), 2011)
      Voltage variations are a major challenge in processor design. Here, researchers characterize the voltage noise characteristics of programs as they run to completion on a production Core 2 Duo processor. Furthermore, they ...
    • Voltage Smoothing: Characterizing and Mitigating Voltage Noise in Production Processors via Software-Guided Thread Scheduling 

      Reddi, Vijay Janapa; Kanev, Svilen; Kim, Wonyoung; Campanoni, Simone; Smith, Michael D.; Wei, Gu-Yeon; Brooks, David M. (IEEE, 2010)
      Parameter variations have become a dominant challenge in microprocessor design. Voltage variation is especially daunting because it happens so rapidly. We measure and characterize voltage variation in a running Intel Core2 ...
    • XIOSim: power-performance modeling of mobile x86 cores 

      Kanev, Svilen; Wei, Gu-Yeon; Brooks, David M. (Association for Computing Machinery, 2012)
      Simulation is one of the main vehicles of computer architecture research. In this paper, we present XIOSim - a highly detailed microarchitectural simulator targeted at mobile x86 microprocessors. The simulator execution ...
