Design Of Inductive Coupling Interconnect Channel And Fault Tolerant Routing Algorithm In 3D-NoC

Compared with other interconnection technologies,inductively coupled wireless interconnection technologies have many advantages that are unmatched in terms of cost,performance,and scalability.But power consumption has become one of the bottlenecks in the development of 3D-NoC technology.The research on 3D-NoC power management and power control technology based on inductively coupled wireless interconnection has important theoretical value and research significance.The traditional Standard Inductive Coupling(SIC)operating frequency is generally much lower than the resonant frequency of the inductor itself.Based on this,a Resonant Inductive Coupling(RIC)wireless interconnect channel is proposed in this paper to solve the problem of poor performance due to the low magnetic flux between the coupled inductors.Under weak and strong coupling conditions,compared with SIC,the current and voltage gains of RIC wireless channels can be increased by Q~2 and 2Q times(Q is a quality factor),and their power transfer performance is also significantly improved compared with SIC.The simulation results of HFSS show that the peak energy transmission efficiency of RIC can reach 54%,while the peak power transfer efficiency of SIC is generally less than30%.For the problem that the routing process is blocked and power consumption increased in the routing process by the existence of the faulty node,this paper designs a 3D-NoC routing fault-tolerance algorithm based on zone defense.The algorithm is based on the fault model of Convex Block Fault in 2D-NoC,and establishes defense zones for different fault models.The routed data packets can avoid passing through the faulty cube and achieve more efficient routing by getting the location of the faulty body informed in advance.After simulation,it was found that when the 3D-NoC system reaches saturation,the 3D-NoC routing fault-tolerance algorithm based on regional defense has better performance than the3D odd-even steering algorithm.The throughput and delay performance can be improved by 23%and 24.4%respectively and the total power consumption of the system is reduced by 20.7%under saturation conditions.In order to more accurately simulate the power transfer performance of the inductively coupled wireless interconnect 3D-NoC,this paper proposes an inductively coupled 3D-NoC power consumption model and transforms Noxim and co-simulates with the Orion power simulator.The simulation results show that the total system power consumption of RIC and SIC wireless interconnect 3D-NoC can be reduced by 26%and 35.4%compared to TSV physical interconnect 3D-NoC.Compared to SIC Wireless Interconnect 3D-NoC,RIC Wireless Interconnect 3D-NoC increased the system's power transmission efficiency from14%to 34%.
