Abstract

Double base number systems are increasingly attractive for many compute intensive applications especially in signal processing because of their capabilities of handling arithmetic operations efficiently. However, the complexity involved in converting binary to DBNS becomes a major bottleneck and the efficiency of performance goes down drastically due to the complexity involved in conversion . Since complexity of multi digit DBNS multiplications and additions increases with the number of digits ( index i ,j) ,in this paper a novel conversion scheme has been proposed where a given binary number will be converted to a single digit (index i ,j) double base number . The proposed scheme not only reduces the hardware complexity of the arithmetic operations but also reduces the time of execution.
