Gigabit Ethernet 802.3 MAC - Media Access Controller

Overview

The Gigabit Ethernet Media Access Controller with AHB Interface IP core is compliant to the Ethernet/IEEE 802.3-2008 standard. The Gigabit Ethernet - AHB IP Core provides a 10/100 Mbps Media Independent Interface (MII), a 1000 Mbps Gigabit Media Independent Interface (GMII), and an AHB master/slave interface. The Gigabit Ethernet IP Core is designed for SoC and mobile applications such as integrated networking devices, PCI-Express Ethernet controllers, and Ethernet adapter cards.
