ABSTRACT
<p>A systematic derivation of a radix-4 square-root algorithm using redundant residual and result is presented. Unlike other similar schemes it does not use a table lookup or PLA for the initial step, resulting in a simpler implementation without any time penalty. The scheme can be integrated with division and incorporates an on-the-fly conversion and rounding of the result, thus eliminating a carry-propagate step to obtain the final result. The result-digit selection uses 3 bits of the result and 7 bits of the estimate of the residual.</p>
