Hello everyone, I'd like to add some custom interface to several IPs of my design (these IPs would act as a kind of firewall). I'm gonna explain it if it's not clear :
Instead of having my IP (or my Microblaze) directly connected to my PLB bus, I want to connect it to a custom interface first. The order will be "IP/Microblaze<=>Custom Interface<=>PLB Bus". Therefore, it will be easy to add this system if I made my own IP.
I've seen some things within the appnote 529 where the FSL bus is used to create a custom block between the bus and the microprocessor. But it's only for a microprocessor.
Do you see any other possibilities to add these interfaces to existing blocks ?
