Is that for a decoder that can decode multiple instructions per clock cycle? I think it would be somewhat interesting for a single instruction decoder but it would be quite remarkable for a decoder of greater width since x86 instructions aren't even self synchronizing (you can read the same sequence of bytes in different valid ways depending on where you start) while ARM is fixed width.



There are two, Berkeley's BOOM and another from Macaque Labs in India (SHAKTI OO core).


Those don't seem to be tiny x86 decoders, as far as I can tell.
