Xmos link to FPGA

[Folknology]

I cannot seem to find it but remember that some work had been done in using Xmos links to FPGA. I am looking at the best way to connect Xmos chips to an FPGA if anyone has done this or has links to things that may be helpful..

Hi Al,

I will work on some exciting new developments regarding this topic in the upcoming months.
If you want I can inform you by private message.

Thanks Bianco

Please do DM me I would be very interested, I notice in your optical link it was vhdl based will this be similar or is there a possibility of it being Verilog based?

regards
Al

I found this implementation:

It may be related to the project mon2 mentioned

Thanks Larry, that looks interesting, will check it out, don't think it's related as this is verilog..

I can confirm that the xlink code on GitHub works fine, I use it daily between my XS1/XS2 and Altera/Xilinx FPGAs. I added 9-bit FIFOs to the input and output paths and access the link through two 16-bit registers. The management of control characters (HELLO,EOM..) and of credits is done in software by the linux driver.
