Improving the Throughput of Asynchronous On-chip Networks with SDM
Wei Song, D. Edwards · 2010
NoCs have several advantages over their clocked counter-parts. Virtual channel (VC) is the most utilized flow control method in asynchronous routers but spatial division mul-tiplexing (SDM) achieves better throughput performance for best effort traffic than VC. A novel asynchronous SDM router architecture is presented. Area and latency models are provided to analyse the network performance of all router architectures including wormhole, virtual channel and SDM. Network performance shows that SDM routers outperform VC routers in both throughput and area overhead. I.
