12.2.6.6. FPGA-to-HPS bridge

This 256-bit bridge allows logic in the Fabric to perform either non-coherent or IO coherent access to targets in the HPS, access HPS peripherals, and OCRAM. The interface supports the ACE-lite protocol which adds the capability to perform atomic operations in the interconnect. The clock comes from the Fabric, and crosses asynchronously into the APS domain.
