4.1. 10/100/1000 Ethernet MAC
The 10/100/1000 Ethernet MAC function handles the flow of data between user applications and Ethernet network through an internal or external Ethernet PHY. Altera offers the following MAC variations:
- Variations with internal FIFO buffers—supports only single port.
- Variations without internal FIFO buffers—supports up to 24 ports and the ports can operate at different speeds.
- Small MAC—provides basic functionalities of a MAC function using minimal resources.
Refer to 1/100/1000 Ethernet MAC Versus Small MAC for a feature comparison between the 10/100/1000 Ethernet MAC and small MAC.
The MAC function supports the following Ethernet frames: basic, VLAN and stacked VLAN, jumbo, and control frames.
