摘要

A VLSI microrchitecture of a network-on-chip (NoC) router with a wormhole cut-through switching method is presented in this paper. The main feature of the NoC router is that, the wormhole messages can be interleaved (cut-through) at flit-level in the same buffer pool and share communication links. Each flit belonging to the same message can track its routing paths correctly because a local identity-tag (ID-tag) is attached on each flit that varies over communication resources to support the wire-sharing message transportation. Flits belonging to the same message will have the same local ID-tag on each communication channel. The concept on-chip microarchitecture, performance characteristics and interesting transient behaviors of the proposed NoC router that uses the wormhole cut-through switching method are presented in this paper. Routing engine module in the NoC architecture is an exchangeable module and must be designed in accordance with user specification i.e., static or adaptive routing algorithm. For quality of service purpose, inter-switch data transfers are controlled by using link-level overflow control to avoid drops of data.
