<p>An arithmetic operation, such as an SRT computation of a division, square root, addition, subtraction or multiplication, in a data processing unit (216), preferably by iterative digit accumulations, is proposed. An approximate result of the arithmetic operation is computed iteratively. Concurrently, at least two supplementary values of the approximate result of the arithmetic operation are computed, and the final result selected from one of the values of the approximate result and the at least two supplementary values of the arithmetic operation depending on the results of the last iteration step. A multiplexing unit may select the final result. Iteration may use accumulating digit values concatenated to previous results using a radix.</p> |
