    pretty new to this whole computer architure thing, so i appreciate the answers given to my previous question, went through a lecture today in class, came out pretty clueless....what i would like to know is

    how exactly would the block diagram for a four bit adder circuit look? thank you for your time once again.

    Welcome to the PF. This is something that you should be researching and reading about on your own. You need to learn how to learn, in addition to learning the material. Try looking in your textbook, or go to wikipedia.org and do a quick search. You will find plenty of learning materials there for this topic.

    If you don't understand something about what you've read, by all means ask a question here showing what you don't get (a link or a quote, for example).

    EDIT -- In fact, can you show us a block diagram of the adder circuit you are asking about? That would be a good exercise for you. :biggrin:

    hahahaha okay okay...i guess it would make more sense for me to research it huh but thanks for your response and i will try and figure it out.

    Alternatively, a truth table for the sum s and the carry bit co for the addition of two 1-bit numbers a and b could be illuminating... :wink:
