Outline of Final Research Achievements

We established fundamental techniques to build various types of chip combination using inductive coupling through chip interface (TCI). In order to build chips with TCI easily, IPs (Intellectual Properties) from the physical layer to the router layer were developed and openly distributed. Several prototype chips including CPU, accelerators and memory were designed and implemented. Performance and power optimization and adaptation techniques for stacking multiple chips have been investigated. The thermal analysis has been done for chip stack with TCI. The shared buses and point-to-point networks with TCI were investigated. Finally, control software for a system with heterogeneous accelerators were developed.
