Computers problem

  1. Jul 26, 2008 #1
    There is this system which is build out of 2 units (2 CLA units) and the question is, what does it do?

    The input numbers are X and Y, which both have 4 digits (binary) each (x0, x1, x2, x3 and y0, y1, y2, y3) and x0y0 for example is an AND gate.

    Any idea, anyone?
    Is this the right forum to post this kind of question?

    Actually, it belongs in the Homework Help forums. I'll move it there for you.

    Please tell us your thoughts about what you think is going on. Why would you use a number of Full Adders like that?

    What do you mean, what do I mean. I'm asking you for your ideas and thoughts about what those block diagrams look like. Why would you be combining multiple Full Adders? What kind of functions would you use combinations of Full Adders for? Maybe look up Full Adder on wikipedia.org, and see what they show as applications for FAs....

    I know what full adder does, I know what CLA system is.

    The thing I don't know is, the purpose of this system.

    I ran a lot of combination but still came out short, found nothing...
