10/100/1000 Ethernet MAC (GEMAC) IP *
The GEMAC is a highly configurable 10-Gigabit Ethernet MAC core for use in Gigabit Ethernet chip designs. The hardware configurable features allow the core to be used in switching, routing, uplinks, server adapters and other SOC applications.
The Gigabit Ethernet Controller core implements a Medium Access Controller (MAC) and associated user application interface. It is designed to comply with the IEEE802.3ae to meet the requirements for both WAN/MAN and LAN connectivity. It provides automatic flow-control implementation (Pause frames) as well as support for virtual bridged LANs (VLAN, 802.1Q) offering usage in a wide area of applications.
