Abstract
PURPOSE: To obtain an information processor featuring such constitution in that at least one unit of the adders is formed with the carry propagation/maintenance adder and thus this doulbe-purpose adder can substitute the faulty adder if any.
CONSTITUTION: The multiplicand and the multiplier to be applied to multiple gate 14 and decoder 13 receive the multiplication through the circuit including carry preservation adder 15, carry propagation/maintenance adder 16 plus carry propagation adders 17 and 18 each. And the arithmetic result is set to register 23. The above-mentioned multiplication is performed via the routes shown by the dotted lines. Now if adder 18 becomes faulty, adder 16 functions as adder 18 in the cycle of its operation. And the routes are switched as shown by the dotted lines. Thus adder 16 can substitute adder 18.
