Abstract: The on-chip network architecture design is completely rule-based or purely application-oriented.The former has unilaterally considered regular structure advantages,while the latter possesses unilaterally considered the application-oriented advantage.The both can not all be taken into account in the same time.This paper proposes a design method of a new communications structure for the Long-Range Link inserting in the appropriate rules topology and discusses its potential of improving the performance of the NoC.The proposed method enables the improvement of the iterative algorithm of intelligent insertion of long chain.Simulation result indicates that the improved topology can effectively delay the network congestion,significantly reduce the network latency,and improve the system throughput with less resource consumption.The improved intelligent insertion algorithm can effectively avoid the local optimal solution and get a better global optimal solution.
