1. A microprocessor which is programmed to determine a minimum one of at least two binary values, comprising:

  • a first adder which is configured to add upper bits of a first binary value with inverted upper bits of a second binary value, said first adder configured to provide a first carry output and a first propagate output;

    wherein said first adder is configured OR each bit of said upper bits of said first binary value with a corresponding bit of said inverted upper bits of said second binary value to provide a plurality of result bits and is configured to logically AND said plurality of result bits to provide said first propagate output;

    a second adder which is configured to add lower bits of said first binary value with inverted lower bits of said second binary value, said second adder configured to provide a second carry output; and

    a compare circuit which is configured to determine whether said first binary value is greater than said second binary value based on said first and second carry outputs and said first propagate output.
