Evaluation of a Non-intrusive packet delivery monitoring service on Networks-on-Chip

Abstract

We present the design and evaluation of a non-intrusive packet delivery monitoring service on a Network-on-Chip (NoC) that focus real-time systems. Recent works show that using adaptive routing or optimization techniques are solutions to improve its latency. These strategies usually need to know the traffic behavior previously to make changes. A monitoring service is indicated as a solution to this issue, but since silicon consumption is a restriction in these projects, most of them use routers or other NoC's resources to performer such task. Our design is based on a strategy that does not interfere with the NoC operation to collect and to evaluate traffic information.
