WebIn this work, we propose the use of high-radix networks in on-chip interconnection networks and describe how the flattened butterfly topology can be mapped to on-chip networks. By using high-radix routers to reduce the diameter of the network, the flattened butterfly offers lower latency and energy consumption than conventional on-chip topologies. WebOct 28, 2024 · The present work proposes an NoC topology taking into account the above design considerations. Rigorous experimentation is done with prevalent counterparts like mesh, torus, flattened-butterfly, butterfly-fat-tree, etc. Low network diameter and sufficient path diversity come up with a minimum of 38% latency improvement among all the cases. descor limited partnership
