Abstract: This paper proposes sphere-based topology for networks-on-chips. The sphere-based topology is a new structure for network-on-chips that forms in sphere shape. The proposed topology is introduced and compared with existing ones in regard of factors such as power and. We have compared the performances of sphere-based topology with two other common topologies namely mesh and torus. Based on the simulation results, the sphere-based topology is better than the two others in latency and power consumption comparison.

Keywords: network on chip; NoC; sphere topology; routing; performance evaluation; power consumption; latency; simulation.
