Animation showing how a combination of logic gates perform addition of numbers. The initial arrangement of two XOR gates, two AND gates and an OR gate is called a full adder, shown in clip K007 6879. The full adder is boxed and added to three identical units. Blue digits show the base ten numbers represented by the binary numbers in the red digits. Each full adder has two controllable inputs (above) and one input from the adder to its right in the row. Each adder sums its inputs, and carries a significant figure to its left if the result is more than one. This adds the binary numbers of the two rows of inputs. Inside an electronic calculator, this array of adders is formed on an integrated circuit, which is itself embedded on a printed circuit board, which connects the integrated circuit to a battery, display screen and input keys. See clip K007 7620 for more adders inside an electronic calculator. | |
