Alternative interconnects are attractive for scaling on-chip communication bandwidth in a power-efficient manner. However, efficient utilization of the bandwidth provided by these emerging interconnects still remains an open problem due to the spatial and temporal communication heterogeneity. In this article, a Stream Arbitration scheme is proposed, where at runtime any source can compete for any communication channel of the interconnect to talk to any destination. We apply stream arbitration
