13.3. System Interconnect and Firewalls System Integration

The system interconnect consists of connection points, datapaths, and the service network.

  • Connection points interface the interconnect to initiators and targets of other HPS components.
  • Datapath switches transport data across the network, from initiator connection points to target connection points.
  • Service network allows you to update initiator and target peripheral security features and access interconnect registers.

The system interconnect is also connected to the cache coherency unit (CCU). The CCU provides additional routing between the MPU, FPGA-to-HPS bridge, MPFE, GIC, and on-chip RAM.

The following figure shows the high-level block diagram showing the L3 and L4 interconnects.
