Gagan, N.Bhowmik, B.2026-02-062021IEEE Region 10 Annual International Conference, Proceedings/TENCON, 2021, Vol.2021-December, , p. 875-88021593442https://doi.org/10.1109/TENCON54134.2021.9707355https://idr.nitk.ac.in/handle/123456789/30251With the increase in the network size, the conventional network-on-chip (NoC) imposes high latency due to the lack of shorter paths between far nodes resulting in performance degradation. This paper proposes an alternative approach that improves performance for long-distance communication in a mesh NoC. The proposed method explores a new topology named 'pseudo-3D mesh' in which a few new nodes are added in the upper layer of a 2D mesh NoC. Experimental results show that the proposed scheme provides acceptably high performance at the cost of little hardware over-head. © 2021 IEEE.Long-distance CommunicationNetwork PerformanceNetwork-on-ChipPseudo-3D MeshTopology Exploration
