Saturation detection in floating point to integer conversions

摘要

An improved method and apparatus for saturation detection in floating point to integer conversions is described. A floating point number is tested for saturation conditions based on an integer field size. From testing the saturation conditions on the floating point number, the present invention predicts whether a floating point number can be converted into an integer value having the given integer field size, or whether the integer field would be saturated. In one embodiment, the saturation conditions are tested on the floating point number in parallel with a floating point to integer conversion.
