By Ron Ho,Philip Amberg,Eric Chang,Pranay Koka,Jon Lexau,Guoliang Li,Frankie Y. Liu,Herb Schwetman,Ivan Shubin,Hiren D. Thacker,Xuezhe Zheng,John E. Cunningham,Ashok V. Krishnamoorthy
Issue Date:January 2013
pp. 68-78
Optical interconnects play an integral role in large-scale digital computing, switching, and routing systems. The authors describe a path toward future many-chip modules based on silicon photonic interposers that stitch together tens of chips in a dense an...
 
Wavelength stealing: an opportunistic approach to channel sharing in multi-chip photonic interconnects
Found in: Proceedings of the 46th Annual IEEE/ACM International Symposium on Microarchitecture (MICRO-46)
By Arslan Zulfiqar, Mikko Lipasti, Pranay Koka, Xuezhe Zheng, Ashok Krishnamoorthy, Herb Schwetman
Issue Date:December 2013
pp. 222-233
Silicon photonic technology offers seamless integration of multiple chips with high bandwidth density and lower energy-per-bit consumption compared to electrical interconnects. The topology of a photonic interconnect impacts both its performance and laser ...
     
A micro-architectural analysis of switched photonic multi-chip interconnects
Found in: Proceedings of the 39th Annual International Symposium on Computer Architecture (ISCA '12)
By Ashok V. Krishnamoorthy, Chia-Hsin Owen Chen, Herb Schwetman, Kannan Raj, Michael O. McCracken, Pranay Koka, Ron Ho, Xuezhe Zheng
Issue Date:June 2012
pp. 153-164
Silicon photonics is a promising technology to scale offchip bandwidth in a power-efficient manner. Given equivalent bandwidth, the flexibility of switched networks often leads to the assumption that they deliver greater performance than point-to-point net...
     
Silicon-photonic network architectures for scalable, power-efficient multi-chip systems
Found in: Proceedings of the 37th annual international symposium on Computer architecture (ISCA '10)
By Ashok V. Krishnamoorthy, Herb Schwetman, Michael O. McCracken, Pranay Koka, Ron Ho, Xuezhe Zheng
Issue Date:June 2010
pp. 72-ff
Scaling trends of logic, memories, and interconnect networks lead towards dense many-core chips. Unfortunately, process yields and reticle sizes limit the scalability of large single-chip systems. Multi-chip systems break free of these areal limits, but in...
