IP that can convert memory mapped I/F to AXI

Hi,

 

I need an IP that can convert memory mapped I/F to AXI I/F.
Where can I find such an IP?

 

Thank you

Re: IP that can convert memory mapped I/F to AXI

Meaning I need an IP to which I can give an write address and write data and the IP will convert it to AXI transaction.

As far as I know there is not any IP that does exactly what you want, at least not in the Vivado IP catalog. But you can use the AXI Protocol Converter IP to convert from AXI4 to AXI4 Lite, and then design your own logic to interface with the AXI4 Lite interface. The protocol is really quite simple and the logic is not difficult. You may even be able to get someone to post some example code for you.

Is there an IP that does the oposite conversion?

If you go through the IP Packager flow, it gives you an option to create a AXI or AXI Lite peripheral which does what you are asking for. Check out UG1118 for more

Hello,

 

You said:

...

That's exactly what the IP Packger does when you tell it tha tyou want an AXI interface. It generates code for you that converts from/to AXI interface.

I wonder do you have any suggestion about pdf to text conversion? Something went wrong with my pdf reader. Thanks in advance.
