ABSTRACT:
An arithmetic and logic operation system capable of performing an arithmetic and logic operation for data longer than one word, includes an arithmetic and logic unit for performing an arithmetic and logic operation for a less significant one-word length portion of the data, and an incrementer/decrementer for incrementing or decrementing of a more significant data portion exceeding the one-word length of the data. A carry signal or a borrow signal generated in the arithmetic and logic unit is supplied to the incrementer/decrementer so that the incrementer/decrementer is controlled so as to selectively increment, or decrement the received data or alternately to output the received data without modification.
