The HPS-to-FPGA interface is a configurable data width AXI master (32-, 64-, or 128-bit) that allows HPS masters to issue transactions to the FPGA fabric.
The lightweight HPS-to-FPGA interface is a 32-bit AXI master that allows HPS masters to issue transactions to the FPGA fabric.
Other interface standards in the FPGA fabric, such as connecting to Avalon-MM interfaces, can be supported through the use of soft logic adapters. The Platform Designer (Standard) system integration tool automatically generates adaptor logic to connect AXI to Avalon-MM interfaces.
Each AXI bridge accepts a clock input from the FPGA fabric and performs clock domain crossing internally. The exposed AXI interface operates on the same clock domain as the clock supplied by the FPGA fabric.
