Hmm. I haven't read this article, so I'm simply speculating here.
I find it VERY hard to believe that someone has made a general purpose
microprogrammed RISC that is faster at being a 486 than a 486 itself.
For one thing, one of the main "definitions" of RISC is that it's not
a microcoded machine. I know, everyone has their own opinion in the
RISC/CISC debate, but I'd personally rather hear something like
"pipelined CISC" than "microcoded RISC". Please don't send me flame
mail for that.
Next, unless a major chip manufacturer is fabing the chip, I'd doubt
that they could get the cost down to $10. It's probably costing Intel
more than that to make the 486. Also, their useful yeild would be
really low for a while, making the cost initially high.
Next, if you can make a general purpose chip that can emulate an
'816, then you can ALWAYS make a dedicated '816 that'll be faster.
Why not just do that?
Oh well. I just wanna get an Alpha to go with my Alfa...
Lastly: everything I've said in this post is MY OPINION. I haven't
read the article, so PLEASE don't send me mail saying that I'm wrong,
and the chip does exist.
