Quality of Service (QoS) for Asynchronous On-Chip Networks

T. Felicijan, S.B. Furber


Quality of Service (QoS) refers to a capability of a network to provide better service to a particular flow of data and it is a very important feature of modern networks. QoS provision has usually been based on a strict synchronised behaviour of a network where QoS packets traverse the network in prereserved time-slots.

This paper investigates the ability of an asynchronous on-chip network to provide QoS. It discusses the problems of self-timed design to provide guaranteed bandwidth and proposes solutions to the problems.
