ABSTRACT:
Apparatus for determining a value, a sign and an overflow status of an addition of at least three n-bit data inputs. The apparatus comprising: a first adder, for adding the at least three n-bit data inputs, to provide a first output having at least 2n bits; a second adder for adding a portion of bits of the first output, the second adder being operable to add a plurality of m-bit addends, m being smaller than or equal to n. The apparatus further comprising at least two electronic-circuits, operatively associated with the first adder and the second adder. The first adder, the second adder and the at least two electronic-circuits are constructed and designed to obtain the value, the overflow status and a sign of the addition of the at least three data inputs, using predetermined parity rules being associated with a parity characteristic of the at least three data inputs.
