A carry-out bit generator determines if a bit pattern from two positive numbers matches one of the patterns for which a carry-out bit would be generated in addition. These patterns include a T G pattern and a T pattern (with a carry-in). Superscript n represents a number between zero and m−1, superscript m represents the number of registers, T represents a 0/1 or 1/0 pair and G represents a 1/1 pair.
