ABSTRACT:
A method for improving the execution of significant bit scans on a data entity in a computer system is provided. The data entity is examined in a number of iterations equal to the base two logarithm of the size of the data entity in bits, N. Initially, half of the data entity is examined to determine if the significant bit is present. If not, the other half of the data entity is examined. The half within which the significant data entity resides is then iteratively halved and examined in each successive iteration of the method until the number of bits examined is equal to one.
