A Symmetric Odd-Even Routing Model in Network-on-Chip

The performance of adaptive routing strongly depends on its degree of adaptive ness in Network-on-chip (NoC). It is observed that there exists adaptive imbalance between even and odd columns in the well-known odd-even (OE) model. In this paper, we present an improved OE model, called symmetric OE model (SOE), which provides higher level of adaptive ness and uses central deadlock buffers to avoid deadlock. Simulation results show that the proposed SOE routing model distributes traffic more uniformly and achieves performance improvement in terms of network saturation throughput and package latency by 18 and 25 percent respectively on average comparing with the previous work of OE.
