Translation: I like to crap on other peoples accomplishments. I don't realize that adders are simple logic gates for the people who were actually there when 7400 TTL was a new thing and building ALUs out of adders is one of the oldest ways of building them (unlike "cheating" using a 74181, for example). Or that using PROMs to replace logic is just as old. I propose my "better" way of doing things that unlike the OP I'll never actually do, but I get to crap on him. I'm so disconnected from reality (or went to such a low grade school) I don't know that people actually learn how to build CPUs in school, as opposed to this knowledge being imparted from mystical higher beings directly into CPU architects skulls, or some such.

But mostly, I like to crap on other peoples accomplishments.
