Multiplier for non-integral multiplicators

Abstract

The present invention provides a kind of multiplier for non-integral multiplicators, which uses approximation method to carry out multiplication of non-integral values. Based on the approximation method comes out a new structure of fixed-point calculation multiplier, which is suitable for integrated circuit design and can be used in pipe line operation. The precision can be modified according to the actual requirements. Composed of n−1 displacement adder-subtractors and one displacement carrier in tandem, the multiplier is an n-grade multiplier. When a higher precision is required, more displacement adders can be concatenated at the end of the multiplier. Therefore, the number of displacement adders can be increased or reduced according to the design requirements, so as to reach the balance between precision and number of logic gates.
