Sphere based topology: A novel idea for NoCs

Topology has significant effects on the most important parameters of a network such as latency and power consumption. The sphere based topology is a new structure for Network-on-Chips that forms in sphere shape. We have used a Zone-Order label based algorithm for the routing that is a general algorithm for routing requirements, and it is based on spanning tree. We have compared sphere based topology with mesh and torus those are two common topologies. Based on the results, the sphere based topology is the best of the two others in latency and power consumption comparison.
