A Performance Enhanced Dual-switch Network-on-Chip Architecture

Network-on-Chip (NoC) is an attractive solution for future systems on chip (SoC). The network performance depends critically on the performance of packets routing. However, as the network becomes more congested, packets will be blocked more frequently. It would result in degrading the network performance. In this article, we propose an innovative dual-switch allocation (DSA) design. By introducing two switch allocations, we can make utmost use of idle output ports. Experimental results show that our design significantly achieves the performance improvement in terms of throughput and latency at the cost of very little power overhead.
