Abstract: Performing an arithmetic operation in a data processing unit, including calculating a number of iterations for performing the arithmetic operation with a given number of bits per iteration. The number of bits per iteration is a positive natural number. A number of consecutive digit positions of a digit in a sequence of bits represented in the data processing unit is counted. The length of the sequence is a multiple of the number of bits per iteration. A quotient of the number of consecutive digit positions divided by the number of bits per iteration is calculated, as well as a remainder of the division.
