Abstract
A novel method and apparatus is disclosed for locating the first most, or least, significant set bit in a bit-string. The present invention breaks down the bit-string into a plurality of shorter sub-strings so that boolean operations can be performed directly to the shorter sub-strings for determining the location of the most/least significant set bit. Furthermore, this method can be repeatedly used to reduce the length of the shorter sub-string after the most/least significant sub-string is located. Particularly, this method of repeatedly dividing the bit-string greatly increases the speed of locating the set bit.
