Hello,
I have searched and searched the internet for quite a while, and I still can't figure this out. Could anyone explain to me how an adder with fast carry generation works, and possible provide a schematic?
Thanks,

You could not have searched very efficiently

these article were on the first google page.

If you are designing silicon you might consider the propagate-kill block described in Mead and Conway, VLSI Design, 1980

 

Ok,
Awesome, thanks so much.
