40GbE TCP Off-loading Engine(TOE40G-IP) IP core is the epochal solution implemented without CPU. Generally, TCP processing is so complicated that expensive high-end CPU is required. TOE40G-IP built by pure hardwired logic can take place of such extra CPU for TCP protocol management. This IP product includes reference design for Intel FPGA. It helps you to reduce development time. DesignGateway provide demo file for Intel FPGA boards. You can evaluate TOE40G-IP core on real board before purchasing.


  • TCP/IP off-loading engine for 40Gbit Ethernet
  • Supports Full Duplex communication
  • Support both Server and Client mode (Passive/Active open and close)
  • Provide free evaluation sof file for FPGA Development Kits (1 hour time limited)
  • Reference design is included in IP core product
