There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is to promote a multi-physics co-design methodology for three-dimensional (3D) processors to achieve high performance gain and energy efficiency. Toward this goal, the proposed work explores the co-design possibilities in a 3D multi-core processor from three perspectives. The first part of the proposed work looks into the thermal-architecture co-design that develops thermal-aware adaptation mechanisms in 3D processors to improve energy efficiency. The second part of the work focuses on the power-architecture co-design that reduces the runtime power consumption by minimizing the guard band of the supply voltage with predictive data from architectural level. The last part of the work proposes the package-architecture co-design that explores the effective combination of asymmetric cores based on the characterization of 3D packages. By evaluating the effectiveness of these approaches, this research wishes to establish the value of multi-physics co-design as an integral part of future processor design.
