2.1.11. Reconfiguration Interfaces
- The datapath Avalon® memory-mapped interface can access 400G hard IP (MAC, PCS, and FEC), 200G hard IP (PCS and FEC), EMIBs (both tile and core sides), PMA interfaces, and control and status registers (CSRs) implemented in the FPGA core.
- The PMA Avalon® memory-mapped interface can access PCIe* hard IP and PMAs.
There is one reconfig_pdp per hard IP instance and one reconfig_xcvr per PMA. reconfig_pdp provides the parallel datapath interface of both 400G hard IP and 200G hard IP access to the datapath Avalon® memory-mapped interface. reconfig_pdp is specific to Direct PHY IP. Other interfaces may use different naming. Ethernet, for example, uses reconfig_eth.
