Does CHI protocol interface use pipelines or register slice to support long distance connections ?

armchronos

Hi,

I assume CHI needs to either pipeline or implement something like the AXI register slice to support long distance connections.

Please confirm and where can I find relevant information for this topic.

Thanks,

David

    I don't believe there's any official documentation on this subject.  It's left up to an implementor to interpret the specification and design an appropriate method for registering the various signals.

    At a very high level, this should be simpler than AXI.  As a starter, would need some control logic to manage the link credits and valids at the input and output, and some sort of payload register.
