Abstract
A normalizing circuit is disclosed which can make bit shift operation for a bit string. The normalizing circuit has a leading 'one' detector, an encoder and a bit shifter. The leading 'one' detector detects a bit position of a leading 'one' among a bit string and produces a signal to indicate the bit position of the leading 'one'. The encoder produces a control signal by which bit shift operation is executed. The bit shifter has a plurality of shift paths to shift leftwardly or rightwardly the bit string such that the leading 'one' bit is positioned at the most left position or the most right position. One of the plurality of shift paths is selected by the control signal produced by the encoder. Thus, bit shift operation of the leading 'one' bit can be executed at a high speed.
