3D NoCs, Routing, Genetic algorithm, Congestion

Network on chip is a new concept in SoC interconnections, this structure facilitate complex components integration. However, as its a new technology, it requires efforts in research, especially for the acceleration and simplification of design phases.NoCs can be arranged in different topologies, such as ring, mesh and torus. Because several data packets can be transmitted simultaneously through the network, an efficient routing strategy must be used in order to avoid congestion delays. In this paper, we study the performance of routing with a genetic algorithm in NoC with 3D mesh topology. The routing is driven by the minimization of total latency in packets transmission between tasks. The simulation results show the effectiveness of the Genetic routing by comparing it with other types of routing.
