Improving BE traffic QoS using GT slack in NoC systems

Recently, network on chip (NoC) architectures are being proposed for implementing multi-core systems for realtime multi-media applications. The communication traffic of those systems will be a mix of guaranteed throughput (GT) and best effort (BE) traffic. GT traffic not only lead to under-utilization of communication links and routers, but also leads to degradation of QoS parameters for BE traffic. We propose a dynamic routing scheme for reducing jitter in the latency of BE traffic affected by the GT traffic. Our results from modeling and simulation indicate that a significant improvement in jitter can be achieved.
