8.1.2.3. System Interconnect Architecture

The system interconnect has a transaction-based architecture that functions as a partially-connected fabric. Not all masters can access all slaves.

The system interconnect is a packet-oriented network on chip (NoC), in which each packet carries a transaction between a master and a slave. The interconnect provides interface widths up to 128 bits, connecting to the L4 slave buses and to HPS and FPGA masters and slaves.

The system interconnect provides low-latency connectivity to the following bridges:

  • HPS-to-FPGA bridge
  • Lightweight HPS-to-FPGA bridge
  • FPGA-to-HPS bridge
  • Three FPGA-to-SDRAM ports
