Method and apparatus for formatting an intermediate result for parallel normalization and rounding technique for floating point arithmetic operations

摘要

The present invention describes an apparatus and method that formats the output fraction result of an ANSI/IEEE 754-1985 floating point arithmetic operation where parallel normalization and rounding of the intermediate fraction result has occurred. The output fraction is formatted using all or some of the bits from the output of either the rounder circuit or the normalizer circuit.
