FAST NORMALIZATION IN A MIXED PRECISION FLOATING-POINT UNIT |
| 摘要 |
A hardware circuit for returning single precision denormal results to double precision. A hardware circuit component configured to count leading zeros of an unrounded single precision denormal result. A hardware circuit component configured to pre-compute a first exponent and a second exponent for the unrounded single precision denormal result. A hardware circuit component configured to perform a second normalization of the rounded single precision denormal result back to architected format. |

1. A method for returning scalar single precision denormal results to double precision normal results in architected format, the method comprising:
counting leading zeros of an unrounded single precision denormal result; pre-computing a first exponent and a second exponent for the unrounded single precision denormal result; and performing a second normalization of the rounded single precision denormal result back to architected format. |
