A Method to Improve Adaptivity of Odd-Even Routing Algorithm in Mesh NoCs

Abstract

Adaptive routing algorithms help balancing the resource utilization in different parts of the network and hence, prevent a resource becoming the performance bottleneck while other resources are still under-utilized. In this paper, we present a novel approach, called Preemptive Waiting, which is applied to Odd-Even routing algorithm (PWOE). PWOE postpones the saturation traffic rate of NoC by 13.4% compared to OE, under synthetic traffic loads.
