Looking for UDP IP stack in VHDL

[Wild Life]

Hello everybody, I'm looking for an UDP/IP stack written in VHDL language (I have to implement it in Spartan-6 FPGA). I'm looking for a one, as simple as possible, with these features:

-written in VHDL language ONLY, not Verilog
-to be implement in a Spartan-6
-no use of other processors or devices (as Microblaze, PowerPC and others)
-no use of external memory, no DDR or external ports, should be use only distributed memory or block ram, no other possibilities
-obviously a free UDP/IP Stack is the best but also a licensed one could be fine

Is there anywhere an UDP/IP stack with these features?

Thank you very much!

if there isnt one on Opencores.org, you may be stuck.

Hello,

I used UDP in a projet. UDP is not hard to implement you can build packets yourself.....

like TrickyDicky said, you can try opencores IP: UDP/IP Core :: Overview :: OpenCores

Re: UDP IP stack in VHDL

ComBlock.com will release a core that meets your requirements this month. The COM-5402SOFT TCP/UDP/IP stack core for Spartan-6 (no external RAM, standard MAC interface) is written in VHDL and includes all the source code. Speed is 1 Gbps running at 125 MHz processing clock. The optional lower layer (MAC) core is available now. The specifications are at comblock.com/download/com5401soft.pdf. I will be glad to answer any question.
