M. S. Chakraborty, S. K. Sao . Comments on ìArea ñ Time Efficient Sign Detection Technique for Binary Signed-Digit Number Systemî proposed by Srikanthan, Lam and Suman. International Journal of Computer Applications. 88, 15 ( February 2014), 38-40. DOI=10.5120/15430-4001
Abstract
It is shown that the sign detection technique for binary signed-digit number system reported by Srikanthan, Lam and Suman [1] cannot work correctly. The root cause of the problem is detected and some modifications are proposed. The proposed modifications are found to be significant.
