A method of modifying a group of full adder circuits to compute a Boolean function of a set number of input bits, each full adder circuit having first and second data inputs, a data output, a carry input and a carry output, the full adder circuits being interconnected so as to form a carry chain. The method comprises the steps of setting the first input of each full adder circuit to a same fixed value, connecting each respective input bit of the set number of input bits to the second input of a respective one of the full adder circuits and using the output of the carry chain of the array of full adder circuits as the result of the Boolean function.
