Improved adaptive routing for networks-on-chip

The degree of adaptiveness has a major impact on the performance of an adaptive routing method. An improved turn model-based routing method that provides a high degree of adaptiveness for a 2D mesh is presented. The proposed method reduces restrictions on the routing turns significantly and hence can provide path diversity using additional routes (both minimal and non-minimal). Experimental results show that the proposed method provides better performance (average latency and throughput) compared with recent routing methods.
