APPARATUS AND METHOD OF PROCESSING NUMERIC CALCULATION |
| 摘要 |
A method and apparatus for processing numeric calculation are provided. The method includes determining a shift bit and an index bit that falls within an index range of a lookup table from among bits representing a divisor scaled up by an offset, obtaining a replacement value corresponding to an index value of the determined index bit by using the lookup table, multiplying a dividend scaled up by the offset by the obtained replacement value, and outputting a value corresponding to a division operation by correcting a scale of a result of the multiplication using a right shift operation. |

1. A method for processing a numeric calculation with a processor, the method comprising:
determining a shift bit and an index bit that falls within an index range of a lookup table from among bits representing a divisor scaled up by an offset with the processor; obtaining a replacement value corresponding to an index value of the determined index bit by using the lookup table; multiplying a dividend scaled up by the offset by the obtained replacement value; and outputting a value corresponding to a division operation by correcting a scale of a result of the multiplication using a right shift operation. |
