  • Abstract
    A method for fast integer division in software, suitable for implementation on processors with integrated hardware multiplier is presented in this paper. It is based on determining divisor´s reciprocal by employing Newton-Raphson equation. Proposed method´s sensitivity to rounding errors and construction of optimal look-up table are investigated. Applied on 16-bit fixed-point division, this method requires only seven arithmetic operations (four multiplications and three additions) and 16-word look-up table
