The Nord SoC features a rich Network-on-Chip topology comprising 19 NoCs including aggregate NoCs, a high-speed configuration NoC (HSCNOC), a multimedia NoC, four NSP data NoCs for AI/ML workloads, PCIe inbound and outbound NoCs, a system NoC, and virtual clock/MC nodes. Bandwidth requests are communicated to the RPMh hardware through Bus Clock Manager (BCM) resources via the Resource State Coordinator (RSC).
