WebExample 1: Four-Bit Carry Lookahead Adder in VHDL. Note that the carry lookahead adder output (o_result) is one bit larger than both of the two adder inputs. This is because two N bit vectors added together can produce a result that is N+1 in size. For example, b”11″ + b”11″ = b”110″. In decimal, 3 + 3 = 6.
