Author here for your 8087 questions. I find adders and ALUs interesting because they are key to the performance of a system and every system implements them differently.
No immediate questions, but happy to have some great weekend reading. A quick pass through finds one of the best and clearest explainers I've seen. Thanks for this and all the materials you produce.
Do you have any insights on how power was delivered to these circuits? Maybe it's done in the metal layers that were dissolved? Also, is it correct that there is no on die capacitance surrounding these circuits?

Any idea how much adder designs changed on modern CPUs compared to back then? I mean there's only so much you can optimize in those, I think...
/* It's a bummer that there is addition but no vipition. */
I knew a guy who bred snakes but could never really get much out of his adders.
Turns out what he needed to do was saw up some tree trunks to make rough platforms for them, and they bred like crazy.
Adders can multiply really efficiently with log tables.

Thanks for the great article.
