Étant donné que la longueur des fils entre les différentes couches, même entre les couches supérieure et inférieure, est suffisamment petite dans un NoC basé sur un maillage 3D (Réseau sur puce tridimensionnel basé sur un maillage), une structure dans laquelle une IP (Propriété de renseignement) dans une certaine couche directement connecté à un routeur approprié dans une autre couche peut réduire efficacement la latence moyenne des messages et augmenter le débit maximum. Avec cette idée, dans l'article, nous introduisons une structure d'accès à double port, dans laquelle chaque cœur IP, sauf celui de la couche inférieure, est connecté à deux routeurs dans deux couches adjacentes et, en particulier, le cœur IP de la couche inférieure. peut être directement connecté au routeur approprié dans la couche supérieure. De plus, nous obtenons l’expression sous forme proche du nombre moyen de sauts de messages et donnons également l’analyse quantitative des performances lorsque la structure d’accès à double port est utilisée. Tous les résultats analytiques révèlent que le nombre moyen de sauts est réduit et que les performances du système sont améliorées, notamment une diminution de la latence moyenne et une augmentation du débit maximum. Enfin, les résultats de la simulation confirment notre analyse théorique et montrent l'avantage de la structure d'accès à double port proposée avec un incrément relativement faible de surcharge de zone.

Abstract: Since the length of wires between different layers, even between the top and bottom layers, is acceptably small in 3D mesh-based NoC (three-Dimensional mesh-based Network on Chip), a structure in which an IP (Intelligence Property) core in a certain layer directly connected to a proper router in another layer may efficiently decrease the average latency of messages and increase the maximum throughput. With this idea, in the paper, we introduce a dual-port access structure, in which each IP core except that in the bottom layer is connected to two routers in two adjacent layers, and, in particular, the IP core in the bottom layer can be directly connected to the proper router in the top layer. Furthermore, we derive the close form expression of the average number of hops of messages and also give the quantitative analysis of the performance when the dual-port access structure is used. All the analytical results reveal that the average number of hops is reduced and the system performance is improved, including a decrease of average latency and an increase of maximum throughput. Finally, the simulation results confirm our theoretical analysis and show the advantage of the proposed dual-port access structure with a relatively small increment of area overhead.
