full hardware (no microblaze) TCP/IP or UDP/IP stack implementation

Jump to solution

Dear all,

Does exists a full hardware (no microblaze) TCP/IP or UDP/IP stack implementation ?

 

For example "Tri-Mode Ethernet MAC v9.0" seems to do not implement a TCP/IP stack.

 

Refer to  PG051 - pag. 14:

" The user side of the MAC is connected to a processor system through a processor DMA engine.

This processor could be running a communications stack, such as the Transmission Control Protocol/Internet Protocol (TCP/IP).

For applications such as this, see the Xilinx Vivado Design Suite: Designing IP Subsystems Using IP Integrator (UG994) [Ref 2].

The IP Integrator contains additional IP to connect the user interface of the MAC to the DMA port of a processor.

The AXI Ethernet Product Guide (PG138) [Ref 3] describes the AXI Ethernet, which can be instantiated for an intended processor application."

 

The proposed solution here is to implement TCP/IP stack via microprocessor.

Even "AXI Ethernet Product Guide (PG138)" mention TCP/IP and UDP/IP about checksum offload feature only.

 

Thanks in advance.

Best regards,
Andrea

Hi @andreac_avnet

 

There is a number of available commercial TCP and UDP IP cores that are implemented entirely in FPGA logic (no processor). Search UDP or TCP on Xilinx IP portal or design-reuse.com

 

It's worth mentioning that TCP/IP stack is much more complex than UDP/IP, and therefore would be more expensive. Another option is to implement your own stack. It's certainly possible, and I've done it myself for one of my past projects.

 

Thanks,

Evgeni

Hi @andreac_avnet

Yes, the only one I have found and used are these Ethernet TCP FPGA Cores.

 

These includes full TCP and/or UDP functionality. They also include remote SPI flash programming and remote debugging with an internal logic analyzer.

Hi @andreac_avnet

 

Yes. I know them.

What target speed do you want to use ?

This company prepare full hardware stack IPs (UDP and TCP) for 40G, 10G and 1G.

These IPs are supported for Xilinx and Intel (Altera).
