Continuous scaling of CMOS expertise makes the integration of large number of heterogeneous devices which results in efficient communication on a single chip. This is the purpose for which competent routers are desirable as a result of which communication takes place between these devices. The proposed methodology gives the method for on-chip routers based on combination of the XY and (Virtual cut through) VCT router for better and optimized data transfer. In this paper the proposed design of on-chip router give the outcome as the optimized routing output because of the priority allocate to the input data packet. The dynamic arbitration technique using VCT and XY is explained in this paper.

Table 1 shows the comparative results of the XY router, and VCT router. As shown in table 1, utilization of number of slices, number of slices flip flop and number of 4 input LuTs in XY is better than VCT. Hence from the above result we can say that XY router results are better than VCT router. The utilization of same parameters is further improved when the combination of XY and VCT router is used. Path selection can be done based on XY routing. We would be selecting a Virtual Channel to pass packets, thus the system would be having advantages of the VCT algorithm. “The authors declare that they have no competing interests.”
