OMG, now that's bummer like it has two PFEs but they share a common XL :)
Now that's got to be the stupidest TRIO design I've seen so far.
I'd love to see how arbitration as well as backpressure is done in this case since now two independent arbiters(since arbiter is in XM) are going to fight over XL resources.
