Each bridge consists of a master-slave pair with one interface exposed to the FPGA fabric and the other exposed to the HPS logic. The FPGA-to-HPS bridge exposes an AXI* slave interface that you can connect to AXI* master or Avalon-MM interfaces in the FPGA fabric. The HPS-to-FPGA and lightweight HPS-to-FPGA bridges expose an AXI* master interface that you can connect to AXI* or Avalon-MM slave interfaces in the FPGA fabric.
