11. Bridges

This chapter describes the bridges used to move data between the FPGA fabric and HPS logic. These bridges make use of Advanced Microcontroller Bus Architecture (AMBA) Advanced eXtensible Interface (AXI) protocol, based on Arteris FlexNoC network-on-chip (NOC) interconnect IP.

This chapter covers the following bridges:

  • FPGA-to-HPS (F2H) bridge
  • HPS-to-FPGA (H2F) bridge
  • Lightweight HPS-to-FPGA (LWH2F) bridge
  • FPGA-to-SDRAM (F2SDRAM) bridge
The following table shows the various Bridges names, acronyms, and alternate terms. You might see some of the alternate terms used in text and figures in this chapter.
