27.4. HPS-to-FPGA Interfaces

The HPS-to-FPGA interfaces provide a variety of communication channels between the HPS and the FPGA fabric. The HPS is highly integrated with the FPGA fabric, resulting in thousands of connecting signals. Some of the HPS-to-FPGA interfaces include:

  • FPGA-to-HPS port
  • HPS-to-FPGA port
  • Lightweight HPS-to-FPGA port
  • FPGA-to-SDRAM interface
