A METHOD AND APPARATUS TO EXTRACT INTEGER AND FRACTIONAL COMPONENTS FROM FLOATING-POINT DATA

摘要

A method is presented including decomposing a first value into many parts. Decomposing includes shifting (310) a rounded integer portion of the first value to generate a second value. Generating (320) a third value. Extracting (330) a plurality of significand bits from the second value to generate a fourth value. Extracting (340) a portion of bits from the fourth value to generate an integer component. Generating (350) a fifth value. Also the third value, the fifth value, and the integer component are either stored (360, 380) in a memory or transmitted to an arithmetic logical unit (ALU).
