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.
Key Features and Benefits
Parameterized AXI slave interface based on the AXI4 or AXI4-Lite specification
Memory mapped direct I/O interface to the transmit and receive data dual port memory
Media Independent Interface (MII) for connection to external 10/100 Mbps PHY transceivers
Independent internal 2K byte Tx and Rx dual port memory for holding data for one packet
Optional dual buffer memories, 4K byte pingpong, for Tx and Rx
