Xmos link to FPGA

Post by 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..

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:

https://github.com/tmbinc/ov/tree/maste ... /src/xlink

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.
