IEEE 1588 hardware timestamping support has been added as an option to the AXI Ethernet Subsystem. This feature is built on the existing functionality provided by the following two cores.
- Tri-Mode Ethernet MAC LogiCORE IP Product Guide (PG051)
- 1G/2.5G Ethernet PCS/PMA or SGMII LogiCORE IP Product Guide (PG047)
Refer, in particular, to the Tri-Mode Ethernet MAC LogiCORE IP Product Guide (PG051) for using the AXI4-Stream interfaces for the datapath, and to the AXI4-Lite interface for configuration and status of the TEMAC core. The additional ports described in this chapter are additional to the user interface ports described therein.
