Communication between components within a chip is essentialfor tasks and deadlines can be met. Network-to-Chipcommunication architectures have become a great option toreplace the bus in this task due to its inherent scalability.One of the One component that may impact the timing ofdata arrival is the arbitration scheme of choice, as the arbitratorshave the function of scheduling packets to be sent tothe next router, depending on some priority criteria. Thispaper focuses on comparing performance between two arbitrationschemes, Round-Robin and virtual channels. Tothis end, dierent trac patterns and dierent injection ratesare tested. Results show that the use of virtual channelscan provide more optimized latency gain solutions and aretherefore suitable for applications with more restricted timeconstraints.
