Ethernet Packet Switch 1G


Comcores Ethernet Packet Switch 1G IP core is an advanced switch supporting buffering of large amounts of data in external RAM. The non-blocking Ethernet switch IP core enables fine-grained traffic differentiation for rich implementations of packet prioritization enabling per port and per queue shaping on egress ports.

The switch supports MAC learning, VLAN 802.1Q, multicast and broadcast as well as IEEE 1588 transparency. Each port provides a native interface for GMII Ethernet PHY devices.
