Overview

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 function 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 using the frame format. On the receiving side, the Ethernet MAC extracts the different components of a frame and transfers them to higher applications through the FIFO interface.
