February 21, 2011 -- In many novel networks-on-chips (NoC) the virtual channels mechanism is widely used. It could be used for different goals from livelocks avoidance to different classes of traffic support.
This mechanism could be differently implemented in hardware. The hardware costs and functional features with virtual channels depend on an approach to its hardware implementation. In this article we consider dependencies between virtual channels hardware implementation features and packet transmission timing parameters in a network-on-chip, as well as possibilities for different classes of services support.
