The AXI Ethernet Lite MAC supports the IEEE Std. 802.3 Media Independent Interface (MII) to industry standard Physical Layer (PHY) devices and communicates to a processor via AXI4 or AXI4-Lite interface. The design provides a 10 megabits per second (Mbps) and 100 Mbps (also known as Fast Ethernet) Interface, delivering the minimal functions necessary to provide an Ethernet interface with the least resources used.
