6.1.1.3. 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.

Each system interconnect 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 interfaces:

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