GNet: A cost-effective architecture reusing generic network service dies

Cost is often the dominant factor for decision making on adoption of a new technology. Moreover, reusing is always a powerful method for cost reduction. GNet - a 3D architecture reusing generic network service dies (GNSDs) - is herein proposed to construct NoCs. GNSDs are known good dies (KGDs) that integrate several networks and can be directly used to bond with other dies in a 3D stack. Flexible and configurable design of GNet makes it suitable to requirements for different systems. A comprehensive cost model, which integrates design cost model, reuse model and fabrication model, is introduced to evaluate different architectures from the design phase to the fabrication phase. Experiments show that the GNet is more cost-effective than general 3D implementations.
