NoC Model Example Instance Sample Clauses

NoC Model Example Instance. Figure 5.10: NoC domain example model Figure 5.10 shows an exemplary model at the NoC-Domain, i.e. the internal structure of an OnChipNetwork. The black connectors at the left and at the upper side of the figure represent the OnChipNetworkInterfaces of the containing OnChipNetwork. The example contains four NoCRouters whose communication interfaces are represented by Input- and OutputUnits. The InputUnits are represented by the white connectors, while the black connectors attached to NoCRouters are OutputUnits, respectively. Note the internal structure of the OnChipNetwork, i.e. the interconnection between the different NoCRouters is modelled using directed connections (arcs) which allows to model complex communication topologies for OnChipNetworks. For instance, this can be used to segregate the communication of the platform components (e.g., Tiles) connected to the corresponding OnChipNetworkInterfaces into different classes. In the topology depicted in the simple example in Figure 5.10 does not impose any restrictions onto the communication flow between Tiles connected to the corresponding OnChipNetworkInterfaces, but provides redundant communication routes. It should be noted, that on all other levels of the platform meta-model, communication links are modelled as undirected connections (edges). Hence – unlike InputUnits and OutputUnits – OnChipNetworkInterfaces are modelled as bidirectional communication elements.
