One of the most trade-off aspects in the design of NoCs is the improvement of the network performance, in terms of throughput and latency, while minimizing power consumption. 2D-mesh has become the preferred topology, since it offers low and constant link delay. This paper proposes a Power efficient, Oblivious, Path-diverse, Minimal routing (POPM) for mesh-based Networks-on-Chip. In order to improve the performance of the network, POPM makes routing decisions locally at each hop rather than establishing a fixed and deterministic path between the source and destination nodes. POPM routes each packet separately through a path selected from among all minimal paths.
