Jump to solution

Hello,

Is there an AXIS FIFO IP available with different input/output data width size?

Thanks.

you can always pack together a 'normal' FIFO and an AXIS resizer at either the input or output.

questions like this are normally IMHO best served by trying the free tools

Not sure I understand your post.

Before posting, I read datasheets of the AXI Stream FIFO IPs available.

Well done for reading the data sheet, You will be amazed how many people will not read them

What I was saying , in too much of a hurry , sorry

Xilinx have free versions of Vivado, the web pack,
if you install that, then you can create a new project, and you get access to the IP catalogue tool in Vivado

The IP tools are great at walking one through the options for each IP, and highlighting the options that are not valid.

So in this case, its easier if you have the tools, just to pop up the IP creator tool for the fifo, and see what you can make

Oh ok. I did that too @drjohnsmith .

That's when I noticed I couldn't have independant port size in the fifos. The datasheets then confirmed.
