Abstract
Division and square root calculations are performed using an operand routing circuit (16) for receiving an operand N, and operand D and a seed value S and directing the operands and seed value to a multiplier (38). Single multiplier (38) is configured into two arrays for calculating partial products of N and S and D and S. The results of multiplier (38) are transmitted through switching circuitry (20) or registers (48) (50) either to operand routing circuitry (16) or adder (44) depending on a convergence algorithm. The final result is rounded.
