Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an on-chip software-defined interconnection network device and method. Background technique [0002] Wafer-level integration has the characteristics of high bandwidth, low power consumption, low latency, low cost, and high density. In order to break the constraints of the boundary conditions of existing large-scale infrastructure systems and solve the current dilemma of large-scale The system (SoC) is upgraded to the system on chip (SoW). Wafer-level integration is "multiplexing" at the silicon chip level, a technology that integrates multiple unpackaged chips on a silicon substrate to replace a PCB. [0003] Interconnects on silicon substrates are the basis for wafer-level integration. Most of the current interconnect technologies on silicon substrates are based on advanced packaging interconnect technologies. Judging from the current various materials and research...
