Abstract
A multiplier unit may be configured to generate a final approximation of an iterative arithmetic operation performed on two operands. Circuitry coupled to the multiplier unit may perform a shift operation and a mask operation on the final approximation to generate shifted and un-shifted approximations, respectively. The circuitry may generate a first remainder using the un-shifted approximation and a sign value of a second remainder using the first remainder. Using the sign value of the second remainder, the circuitry may perform a rounding operation on the shifted approximation to generate a final answer.
