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.
