9.3.1. Functional Description of the FPGA-to-HPS Bridge
The FPGA-to-HPS bridge provides access to the peripherals in the HPS from the FPGA. This access is available to any master implemented in the FPGA fabric. You can configure the bridge slave, which is exposed to the FPGA fabric, to support the AXI protocol, with a data width of 32, 64 or 128 bits. The FPGA-to-HPS bridge multiplexes the configured data width from the L3 interconnect to the FPGA interface.

The FPGA-to-HPS bridge is configurable in the HPS component parameter editor, available in Platform Designer and the IP Catalog. The HPS component parameter editor allows you to set the data path width and the bridge protocol, according to the FPGA bitstream.
