Multicore Model from Abstract Single Core Inputs
Found in: IEEE Computer Architecture Letters
By Emily Blem,Hadi Esmaeilzadeh,Renee St. Amant,Karthikeyan Sankaralingam,Doug Burger
Issue Date:July 2013
pp. 59-62
This paper describes a first order multicore model to project a tighter upper bound on performance than previous Amdahl's Law based approaches. The speedup over a known baseline is a function of the core performance, microarchitectural features, applicatio...
Dark Silicon and the End of Multicore Scaling
Found in: IEEE Micro
By Hadi Esmaeilzadeh,Emily Blem,Renee St. Amant,Karthikeyan Sankaralingam,Doug Burger
Issue Date:May 2012
pp. 122-134
A key question for the microprocessor research and design community is whether scaling multicores will provide the performance and value needed to scale down many more technology generations. To provide a quantitative answer to this question, a comprehensi...
Mixed-Signal Approximate Computation: A Neural Predictor Case Study
Found in: IEEE Micro
By Renée St. Amant, Daniel A. Jiménez, Doug Burger
Issue Date:January 2009
pp. 104-115
<p>As transistors shrink and processors trend toward low power, maintaining precise digital behavior grows more expensive. Replacing digital units with analog equivalents sometimes allows similar computation to be performed at higher speed using less...
Low-power, high-performance analog neural branch prediction
Found in: Microarchitecture, IEEE/ACM International Symposium on
By Renee St. Amant, Daniel A. Jimenez, Doug Burger
Issue Date:November 2008
pp. 447-458
Shrinking transistor sizes and a trend toward low-power processors have caused increased leakage, high per-device variation and a larger number of hard and soft errors. Maintaining precise digital behavior on these devices grows more expensive with each te...
General-purpose code acceleration with limited-precision analog computation
Found in: 2014 ACM/IEEE 41st International Symposium on Computer Architecture (ISCA)
By Renee St. Amant,Amir Yazdanbakhsh,Jongse Park,Bradley Thwaites,Hadi Esmaeilzadeh,Arjang Hassibi,Luis Ceze,Doug Burger
Issue Date:June 2014
pp. 505-516
As improvements in per-transistor speed and energy efficiency diminish, radical departures from conventional approaches are becoming critical to improving the performance and energy efficiency of general-purpose processors. We propose a solution—from circu...
Dark silicon and the end of multicore scaling
Found in: Proceeding of the 38th annual international symposium on Computer architecture (ISCA '11)
By Doug Burger, Emily Blem, Hadi Esmaeilzadeh, Karthikeyan Sankaralingam, Renee St. Amant
Issue Date:June 2011
pp. 365-376
Since 2005, processor designers have increased core counts to exploit Moore's Law scaling, rather than focusing on single-core performance. The failure of Dennard scaling, to which the shift to multicore parts is partially a response, may soon limit multic...
