Abstract
Apparatuses and methods of manufacturing same, systems, and methods for generating a starting estimate for radix-16 square root iterative calculation using hardware, including a radix-4 partial remainder-divisor (PD) table, which is used for both division and square root operations, are described. In one aspect, a part of a radicand for a radix-16 square root iterative operation is used to determine column/root and row/partial radicand values, which are then used to determine a starting estimate from a radix-4 PD table for the radix-16 square root iterative operation.
