ABSTRACT:
An apparatus and method for comparing values A comparator comprising inputting two comparison values to be compared, determining the number of a leading "1" in each of the values and outputting two position values, wherein the position values have a bit size smaller than the comparison values, comparing a first position value of the position values from a second position value of the position values, and outputting a signal indicating a first comparison value of the comparison values is either greater than a second comparison value of the comparison values, equal to the second comparison value or less than the comparison value, based on a result of the comparing operation.
