An alternative scheme of redundant binary multiplier

This work addresses the feasibility of re-engineering the multiplier architecture that is based on a new redundant number representation called the non-carry-propagation (NCP) format to avoid carry propagation. The preliminary theoretical assessments and simulation result show that this multiplier possesses certain revelatory features that make it a potential alternative approach to conventional redundant binary multiplier. The characteristics of NCP number and the structure of NCP adders array are analyzed. A new reverse converter was also proposed to simplify the converter circuit that converts the final redundant binary number into the corresponding 2´s complement number. A recommended gate-level implementation of the multiplier based on this new architecture is also presented.
