Abstract

The routing algorithm benefits from congestionaware flow control, making better routing decisions. Our proposed routing algorithm is architected to fully exploit congestion-aware flow controls which come from neighboring switches and versatile reuse of available resources for concurrent input and output selections to remedy unbalance energy distribution due to peak-power and congested area. We simulate and evaluate the proposed architecture in term of network latency, hardware overhead and energy consumption. Our results show for effectiveness of the proposed technique in balancing the performance and energy of NoC designs.
