Abstract

A novel routing algorithm, named Balanced Adaptive Routing Protocol (BARP), is proposed for NoCs to provide adaptive routing and ensure deadlock-free and livelock-free routing at the same time. By evenly distributing input packets of a router among all its shortest path output ports, a novel adaptive routing protocol for avoiding congestion condition emerges. It is observed that BARP can achieve better performance compared to static XY routing, odd-even routing and dynamic XY routing.
