Cellular Array for Extraction of Squares and Square Roots of Binary Numbers

A cellular array is described that is capable of extracting either the square or the square root of a binary number. The mode of operation is controlled by a single-mode input line. The array is iterative in its connection pattern and is therefore suitable for large-scale integrated (LSI) implementation. Approximate time-delay expressions are derived, which show that the delays for square or square-root extraction are comparable to the, delay of published array networks.
