σLBDR: Congestion-aware logic based distributed routing for 2D NoC

With the advent of multi-core technologies, a significant amount of research has been directed towards running multiple applications concurrently and efficiently. This elevates work load on the network which leads to congestion and subsequently degrades the performance and increases the latency of the network. Table based methods can be used for handling congestion but these methods are not scalable in terms of area. In this paper, we propose a novel routing mechanism that eliminates the need of large routing tables. The results show the performance of σLBDR is better than competing routing algorithms for handling congestion as the area requirement is very less irrespective of the size of the network.
