Abstract
A binary data converter is adapted to convert a positive binary data into a negative binary data represented by a complement on two and vice verse. The conversion is effected as follows. A least significant bit of an inputted binary data is outputted as the least significant bit of the converted binary date as it is. With respect to bit signal other than the least significant bit, respective input bit signals less significant than the corresponding input bit signal are ORed. Depending on the result thereof, inverted or non-inverted signals of the corresponding input bit signals are outputted as the bit signals of the converted binary data. Therefore, carry delay is not generated, and thus the operation speed can be increased. Further, the simple circuit structures can reduce the number of required elements.
