Korotkyi I. Methods of link aggregation and parametric adjustment in wormhole networks-on-chip with two dimensional mesh topology

The object of research is the process of transferring data in wormhole Network-on-Chip (NoC); Purpose - to improve the efficiency of wormhole NoCs with two dimensional mesh topology as the ratio of throughput to hardware costs; Methods: method of least squares, regression analysis and simulation; theoretical results: the method of link aggregation (LAG) for wormhole NoCs is proposed, that improves throughput due to connection of routers with the aid of multiple physical links; the method of parametric adjustment for wormhole NoCs with LAG has been suggested, the essence of which lies in selecting number of physical links per aggregated logical channel proportionally to the degree of its congestion, thus improving the ratio of bandwidth to the hardware costs; the mathematical model of wormhole NoC throughput from the number of virtual channels is proposed; practical achievements: the high performance SystemC model of wormhole NoC with LAG is designed; using System Verilog, two models of wormhole NoC with LAG were developed on RTL and gate levels of abstraction and hardware realization of such a NoC for FPGA Stratix IV has been created; the software implementation of the proposed method of parametric adjustment is developed.
