Over Looped 2d Mesh Topology for Network on Chip

The arrangements of nodes in the network identifies the complexity of the network. To reduce the complexity, a structural arrangements of nodes has to be taken care. The mesh topology yields attraction than the other traditional topologies. Making the opposite corner nodes to communicate with less hops and avoiding the centre of the networks traffic, Over-Looped 2D Mesh Topology is proposed. For a homogeneous systems the proposed work can be deployed without altering any of the switch component compositions. By making the flits, travel in the outer corner nodes with the help of looping nodes will make the journey from source to destination with less hops. For smaller network below 4×4 the looping is less responsive. For odd or even number of columns and rows the looping can be done. The number of columns and number of rows need not to be equal. The left over nodes will be looped accordingly. The hop count of the Over-Looped 2D Mesh Topology compared to 2D mesh decreases the journey by 25%. The wiring segmentation and the wiring length of the system more than 10 % from 2D mesh and less than 20% from 2D Torus.
