At this point I was just trying to se *what is available
for free*. I'd like to find a FREE, like FREE Beer IP Core !
If it comes with it's own beer even better !
I don't care to much about the bus, but I hope to find
something that is instruction order/result accurate.
Trying to find a free solution I can't be to choosy. If
I decide I have to write it myself, I will carefully
evaluate those questions and probably many more.
If I find a free IP core, it might be cheaper/easier to
adjust my application, or perhaps the IP.

You supposed to relax on vacation, not hack ASICs ! ;*)
