Abstract:

A multilevel congestion control (MLCC) network-on-chip routing algorithm was proposed to improve the routing efficiency. When there are medium and high level congestion, MLCC decides how to do congestion control depending on the congestion level difference of the routers. Simulation results show that MLCC maintains low latency than one level congestion control routing algorithms under uniform traffic.

Key words: multilevel congestion control, network-on-chip, routing algorithm
