Abstract :
Centip3De uses the synergy between 3D integration and near-threshold computing to create a reconfigurable system that provides both energy-efficient operation and techniques to address single-thread performance bottlenecks. The original Centip3De design is a seven-layer 3D stacked design with 128 cores and 256 Mbytes of DRAM. Silicon results show a two-layer, 64-core system in 130-nm technology, which achieved an energy efficiency of 3,930 DMIPS/W.
