Fixed point reciprocal algorithm
WebFeb 6, 2014 · Division is an operation extensively used in architectures for digital signal processing algorithms, which in portable devices require an implementation using fixed-point format. In this paper, a novel fixed-point divider is proposed.

Introduction There is a general need for a thorough discussion of the issues surrounding the implementation of algorithms in fixed-point math on the Intrinsity FastMATH processor. WebFeb 10, 2012 · So the first step of the algorithm is to start with an initial guess for 1/D which we call X_0. X_0 is defined as X_0 = 48/17-39/17*D However, we must first apply a bit-shift to the divisor D to scale it so that 0.5 ≤ D ≤ 1. The same bit-shift should be applied to the numerator N so that the quotient does not change.
