9. HPS-FPGA Bridges

This chapter describes the bridges in the hard processor system (HPS) used to communicate data between the FPGA fabric and HPS logic. The bridges use the Advanced Microcontroller Bus Architecture ( AMBA* ) Advanced eXtensible Interface ( AXI* ) protocol, and are based on the AMBA* Network Interconnect (NIC-301).

The HPS contains the following HPS-FPGA bridges:

  • FPGA-to-HPS Bridge
  • HPS-to-FPGA Bridge
  • Lightweight HPS-to-FPGA Bridge
