Redundant binary number appears to be appropriate for high-speed arithmetic operation, but the delay and hardware cost associated with the conversion from redundant binary (RB) to natural binary (NB) number is still a challenging task. In the present investigation a simple approach has been adopted to achieve high speed with lesser hardware and power saving. A circuit level approach has been adopted to implement the equivalent bit conversion algorithm (EBCA) (Kim et al. IEEE Journal of Solid State Circuits 36: 1538-1544, 2001, 38:159-160, 2003) for RB to NB conversion. The circuit is designed based on exploration of predictable carry out feature of EBCA algorithm. This implementation concludes a significant delay power product and component complexity advantage for a 64-bit RB to NB conversion using novel carry-look-ahead equivalent bit converter.
