Add unsigned integers and generate carry.


genUType uaddCarry( genUType x, genUType y, out genUType carry );


x - Specifies the first vector to be used in the summation operation.
y - Specifies the second vector to be used in the summation operation.
carry - Specifies the variable to receive the carry output of the sum.


 uaddCarry adds two 32-bit unsigned integer variables (scalars or vectors) and generates a 32-bit unsigned integer result, along with a carry output. The result is the sum of x and y modulo [math][/math] . The value carry is set to 0 if the sum is less than [math][/math] and to 1 otherwise.
