There was a recent post to the gcc mailing list which showed

I knew a guy with that name at AMD--he did microcode--and did it well.

I think the problem the author is trying to solve is better addressed by
My 66000 (and I would absolutely _hate_ to write an assembler for it).
Still, I thought it worth mentioning.

I took a quick look, and it seems that
a) too few registers
b) too many OpCode bits
although it does look easy to parse.
