Integrated microarchitectural floorplanning and run-time controller for inductive noise mitigation

Michael B. Healy, Fayez Mohamood, Hsien-Hsin S. Lee, Sung Kyu Lim
2011 ACM Transactions on Design Automation of Electronic Systems  
power and current characteristics of running applications.  ...  By dynamically monitoring the access patterns of microarchitectural modules, our mechanism can effectively limit simultaneous switching activity of close-by modules, thereby leveling voltage ringing at  ...  However, the whitespace of the floorplan will be used for decaps to reduce the dI/dt-induced voltage swing.  ...

Mitigating Amdahl's Law through EPI Throttling

Murali Annavaram, Ed Grochowski, John Shen
2005 SIGARCH Computer Architecture News  
Finally, increasing levels of on-chip integration coupled with a slowing rate of reduction in supply voltage make power consumption a first order design constraint.  ...  We also measure the supply current on a 4-way SMP server while running the multithreaded programs and use the measured data as input to a software simulator that implements a more flexible EPI throttle  ...  We would like to acknowledge Carole Dulong and her team for providing us guidance on setting up the BLAST and HMMER programs, Natalie Enright for pointing us to FFTW and Hideki Saito for patiently answering  ...

Wavelet Analysis for Microprocessor Design: Experiences with Wavelet-Based dI/dt Characterization

R. Joseph, Zhigang Hu, M. Martonosi
10th International Symposium on High Performance Computer Architecture (HPCA'04)  
The dI/dt problem has been increasingly vexing in recent years, because of aggressive drops in supply voltage and increasingly large relative fluctuations in CPU current dissipation.  ...  This paper applies wavelet analysis techniques to the problem of dI/dt estimation and control in modern microprocessors.  ...  analysis in the context of the dI/dt problem, and we show how wavelet representations can be used to automatically classify a program's susceptibility to dI/dt-induced supply voltage fluctuations. § We  ...
