28.1.2. FPGA-to-HPS SDRAM Interface

In the FPGA-to-HPS SDRAM Interface table, use + or  to add or remove FPGA-to-HPS SDRAM interfaces.

You can add one or more SDRAM ports that make the HPS SDRAM subsystem accessible to the FPGA fabric.

Parameter Name

Parameter Description

Name

Port name (auto assigned as shown in FPGA-to-HPS SDRAM Port and Iterface Names table)

Type

Interface type:

  • AXI-3
  • Avalon-MM Bidirectional
  • Avalon-MM Write-only
  • Avalon-MM Read-only

Width

32, 64, 128, or 256

Note: You can configure the slave interface to a data width of 32, 64, 128, or 256 bits. To facilitate accessing this slave from a memory-mapped master with a smaller address width, you can use the Intel® Address Span Extender.
