  • Publication number: 20230229391
    Abstract: A normalizer receives input data including first exponent data and first mantissa data and generates normalized output data. The normalizer includes a mantissa alignment circuit, a “1” search circuit, an exponent addition circuit, a normalization circuit. The mantissa alignment circuit outputs second mantissa data including a binary point shifted by one bit to the left in comparison to a binary point of the first mantissa data. The “1” search circuit searches for an uppermost bit position of a leading “1” in the second mantissa data to output shift data. The exponent addition circuit performs an addition operation on the shift data and the first exponent data and configured to perform a “+1” operation on a result of the addition operation to output addition data.
