M S Chakraborty, T Ghosh, A C Mondal . Notes on “A Novel Conversion Scheme from a Redundant Binary Number to Two's Complement Binary Number for Parallel Architectures” proposed by Choo et.al.. International Journal of Computer Applications. 103, 5 ( October 2014), 5-7. DOI=10.5120/18068-9009
In this article, it is shown that although the reverse conversion scheme for binary signed-digit number system proposed by Choo et. al. can not support full parallelism; the rules on which it is based are correct. In this connection, a mathematical induction technique is used to validate the decomposition rules. Accordingly, it can be inferred that the reverse conversion scheme for binary signed-digit number system proposed by Veeramachaneni et. al. works correctly and performs reverse conversion in ? (log n) time, where, n is the input size. As a consequence, the scheme by Veeramachaneni et. al. need to be considered as a potential contender of the more recent schemes for the same.
