The present invention provides apparatus, methods, and computer program products for non-iterative division and non-iterative reciprocal generation. In one embodiment, the present invention uses a logic network that determines the bits of the quotient of a divisor and dividend by using a non-iterative, (i.e., non trial and error), method. Further, in another embodiment, the present invention may determine the reciprocal of a number M by separating the number M into at least two numbers X, Y . . . Z so that M=X+Y+ . . . +Z. The reciprocal of M is computed according to an equation 1/M=F(X,Y . . . Z) or an approximation 1/M&#x2248;G(X,Y . . . Z), where the approximation gives the correct value of the inverse of M to a predetermined accuracy. In some embodiments, the apparatus uses an equation that exactly describes the reciprocal or instead, it may include one or more memories for storing look-up tables containing pre-calculated parts of the equation.
