General Description

Gigabit media-independent Interface (GMII) is an standard Ethernet interface between Media Access Control (MAC) device and Physical Layer (PHY).

So-Logic's Ethernet GMII core implements GMII interface from the IEEE Std. 802.3-2008 specification.

The interface defines speeds up to 1000 Mbit/s, implemented using a data interface clocked at 125 MHz with separate eight-bit data paths for receive and transmit.

The so_ip_eth_gmii core can be evaluated using Xilinx Evaluation Platforms before actual purchase. This is achieved by using a demonstration bit files for KC705 platform that allows the user to connect the So-Logic's complete 1G Ethernet solution system to some other Ethernet enabled device (PC or some Ethernet tester equipment) and evaluate system performance under different transfer scenarios.

For more information about the Ethernet GMII core please consult the corresponding datasheet.
