Slack-time aware routing in NoC systems

—Efficient routing schemes are essential if Network on Chip (NoC) architectures are to be used for implementing multi-core systems for real-time multi-media applications. These systems will be characterized by internal communication traffic which is a mix of traffic requiring guaranteed throughput (GT) and other traffic requiring some other QoS properties like latency and less packet drops. Communication resources are generally reserved for providing GT performance. In this paper we propose a dynamic scheme for improving packet drop probability of other traffic by intelligently utilizing the under-utilized reserved communication resources of GT traffic. We demonstrate the effectiveness of our scheme by simulation.
