Enclustra's UDP/IP Ethernet IP core easily enables FPGA-based subsystems to communicate with other subsystems via Ethernet, using the UDP protocol. The IP core is highly configurable and optimally implemented for the use in current Intel FPGAs and SoCs. It provides a simple to use interface to the user logic, and supports the common media independent interfaces MII, RMII, GMII and RGMII. With its 8-bit wide transmit and receive interfaces running at 125 MHz, the IP core is able to operate at full 1 Gbps wire speed. 100 Mbts and 10 Mbts operation is also supported.


  • Multiple UDP ports with dedicated receive and transmit interfaces for each port
  • Optional receive data buffers
  • Raw Ethernet port for non-UDP communication
  • Header pass-through mode
  • MII, RMII, GMII and RGMII media independent interfaces (full-duplex only)

Device Utilization and Performance

Cyclone® IV, 1 UDP Interface, 2 receive buffer, 2000 byte payload: 3700 Logic Cells, 2700 Registers, 2200 LUT, 11 BRAM (M9k)
