ABSTRACT:
An apparatus and method for performing variable precision floating point rounding operations is provided that accomplishes rounding of a number that is faster, less complex and requires less hardware than conventional devices. The apparatus and method provides for a single uniform incrementer located at the zero position that can add a logic 1 to that position. After the Round, Guard and Sticky bits are produced, logic 1s are inserted in the bit positions to the right of the significant bits of the result with a check unit. The check unit then outputs the intermediate result to an incrementer and a zero-out unit. The incrementer adds a 1 to the zero position and the carry function of the incrementer by operation ripples through the series of 1s up to the rightmost position of the resultant mantissa leaving a trail of zeroes behind producing a first output. Finally, a multiplexer is provided to choose between the first output and the second output as the final result.
