Abstract

An asynchronous router for Quality-of service NoC is presented. It combines multiple service levels (SL) with multiple equal-priority virtual channels (VC) within each level. The VCs are assigned dynamically per each link. A different number of VCs may be assigned to each SL and per each link. The router employs fast arbitration schemes to minimize latency.
