General Description
The Ethernet Media Access Controller (MAC) core can be configured to operate in either the Gigabit mode (1000
Mbits/sec data rate) or the Fast Ethernet mode (10/100 Mbits/sec data rate). Netlist configurations of this core
operate only in either the Gigabit mode or Fast Ethernet mode. The netlist cannot auto-negotiate between the two
different modes.
The Ethernet MAC transmits and receives data between a host processor and an Ethernet network. The main func-
tion of the Ethernet MAC is to ensure that the Media Access rules specified in the 802.3 IEEE standard are met
while transmitting a frame of data over Ethernet. Figure 2 shows the transmission of data on the Ethernet network
– Configurable 8-bit or 16-bit Data Bus Widths
– Full-duplex Control Using PAUSE Frames
– VLAN Tagged Frames
– Automatic Re-transmission on Collision
– Automatic Padding of Short Frames
– Multicast and Broadcast Frames
– Optional FCS Transmission and Reception
– Optional MII Management Interface Module
– Reduced pin count Gigabit Media Independent Interface
