| Abstract(in English) | An efficient method for generating the reciprocal, square root, square root reciprocal, square reciprocal, cube, and so forth of an operand by means of a multiplier with an operand modifier is proposed. The operand modifier performs bitwise complementation, shift and/or redundant binary Booth recoding. The method is a modification of the piecewise linear approximation based on the first-order Taylor expansion. The same accuracy is achieved. The multiplication and an addition required for the linear approximation are replaced by only one multiplication with a modification of the operand. The required table size is reduced, because only one coefficient has to be stored. 1 clock cycle may be saved, because the addition is removed. |
