Abstract

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.
