Ethernet MAC Cores

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 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.

Compliant to IEEE 802.3z Standard Generic Host Interface Configurable 8-bit or 16-bit and Greater Data Bus 16-bit Wide Internal Data Path Full-duplex Operation in Gigabit Mode Full and Half Duplex in 10/100 Mode Transmit and Receive Statistics Vector Programmable Inter Packet Gap IPG Multicast Address Filtering Supports:
