Implementing TCP layer in FPGA

Hello, I need to have a very basic tcp functionality in FPGA which can connect with another machine and transfer payload sent from another hardware module. I am a very beginner in TCP. Is there any opensource stuff that I can use ? I am not sure if there is any HDL resources in TCP. Otherwise, if anyone can refer me to any resource which might help me to code/implement a very basic tcp protocol then it'll be really helpful

    TCP on the hardware level is complicated to implement. AFAIK there is no opensource project, and the commercial alternatives are expensive. It is a lot easier to use a software solution if you want to stick to TCP, or use UDP which is a lot easier to implement in hardware.

    There is a low-cost core available from com block (http://www.comblock.com). Unfortunately it is targeting Xilinx (only), so you will have some work converting e.g. RAM blocks and such.

    skepticc, If this query is related to your other recent threads, and you are simply trying to demo something on a short time frame (and now you want a "Network Enabled" version), you probably just want to use a NIOS using the simple socket server demo app as a starting point.

    If this is a new/unrelated project, as Daixiwen mentioned, you should review if TCP is really necessary. In many cases, UDP is adequate and is hardware-friendly.
