Abstract

Redundant binary (RB) representation is one of the signed-digit number systems originally introduced by Avizienis, which provides carry-propagation-free addition. Since the multiplication of two numbers is generally performed by the addition of partial products, the carry-propagation-free feature of the RB arithmetic can be used to design high-speed multipliers and multiply-and-accumulate units. However, a RB-NB (redundant binary to normal binary) converter is required to provide a 2's-complement representation of the results. Previous research was conducted for the RB-NB converter. In this paper, based on Yen's method and Ling's adder scheme, we propose an improved RB-NB converter. The proposed RB-NB converter shows improvement in area and speed over other methods. The new RB-NB converter has been adopted in our proposed high-performance Complex Arithmetic Signal Processor.
