Power and temperature control on a 90-nm Itanium family processor
R. McGowen,C. Poirier,Christopher J. Bostak,James S. Ignowski,M. Millican,W.H. Parks,S. Naffziger +6 more
TL;DR: This paper describes the embedded feedback and control system on a 90-nm Itanium family processor, code-named Montecito, that maximizes performance while staying within a target power and temperature envelope and presents measured results that show a 31% reduction in power for only a 10% drop in frequency.
Patent
Adaptive algorithm for thermal throttling of multi-core processors with non-homogeneous performance states
TL;DR: In this paper, a power control unit (PCU) is coupled with a thermal control logic to preemptively throttle a first core by a first throttle amount when a temperature of a second core exceeds at least one thermal threshold.
Patent
Methods and systems to detect voltage changes within integrated circuits
Aaron M. Barton,James S. Ignowski,Pablo Lopez,Mondira Pant,Rex Petersen,Robert Rose,Sean M. Welch +6 more
TL;DR: In this paper, the authors propose a method to detect droop events on-chip, which may include a sensor circuit located adjacent to a voltage node to convert a corresponding voltage to a digital count or value indicative of the voltage.
Patent
Power estimation for a semiconductor device
TL;DR: In this article, different embodiments for estimating and/or controlling power consumption in a chip based on hot and cool temperatures in the chip are discussed, as well as different power consumption models for different applications.
Journal ArticleDOI
X-TIME: An in-memory engine for accelerating machine learning on tabular data with CAMs
Giacomo Pedretti,John Moon,Pedro Bruel,Sergey Serebryakov,L. Buonanno,Tobias Ziegler,Cong Xu,Martin Foltin,Paolo Faraboschi,James S. Ignowski,Catherine Graves +10 more
TL;DR: In this article , an analog-digital architecture implementing a novel increased precision analog CAM and a programmable network on chip allowing the inference of state-of-the-art tree-based ML models, such as XGBoost and CatBoost, is presented.
