A Study of NoC Exit Strategies

Abstract

The throughput of a network is limited due to several interacting components. Analysing simulation results made it clear that the component that was worth attacking was the exit bandwidth between the network and the connected resources. The obvious approach is to increase this bandwidth; the benefit is a higher throughput of the network and a significant lowering of the buffer requirements at the entry points of the network; this because worst case scenarios now happens at a higher injection rate. The result we present shows significant differences in throughput as well as in average and worst case latency
