A router-based packet switching network for versatile communication between system on chip (SoC) modules on an integrated chip is known as Network on Chip (NoC). For better communication among intellectual protocols via routers, an effective routing topology along with an efficient router design and an algorithm are required. There are several existing network topologies such as Ring, Mesh, and Star, all of which have drawbacks such as increased diameter, hop- count, wiring etc. This paper suggests a novel routing topology, algorithm and compatible router architecture that provides a path for data from source to destination routers and outperforms mesh and ring topologies in terms of hop count and wiring lengths. Since diagonal paths in the network follows the form of a geometric rhombus, the proposed topology is called rhombic topology. The diagonals in this proposed topology are primarily responsible for lowering the hop count and the distance that data must travel to reach its destination. When implemented in MATLAB and SIMULINK, the results show a 33.92 percent decrease in hop count.
