Stratix Series: Stratix IV


TCP Offloading Engine(TOE1G) IP core is the epochal solution implemented without CPU. Usually TCP processing is complicated and needs an expensive high-end CPU. Because TOE1G IP core automatically takes over all functions of TCP/IP protocol which needs high-speed operation by hardware logic only. This IP product includes reference design for Altera FPGA. It helps you to reduce development time. DesignGateway provide demo file for Altera FPGA Development Kit for evaluation. You can evaluate TOE1G IP core on real board before purchasing.
