Flexibilis Ethernet Switch IP Cores for LatticeECP3 FPGA Devices

Lattice Semiconductor and Flexibilis introduced Flexibilis Ethernet Switch (FES) IP cores for LatticeECP3 FPGAs. The Ethernet switch IP cores can operate at 10Mbps/100Mbps/1Gbps, support Ethernet Layer 2, switch with Gigabit forwarding capacity per port, support Quality of Service with up to four queues per port, and support Gigabit Fiber optic and Gigabit twisted pair copper Ethernet interfaces. The FES IP cores are ideal for smart grid substation automation, networked industrial automation gear, and high availability network equipment.
