Abstract

Systems and methods for generating a floating point constant value from an instruction are disclosed. A first field of the instruction is decoded as a sign bit of the floating point constant value. A second field of the instruction is decoded to correspond to an exponent value of the floating point constant value. A third field of the instruction is decoded to correspond to the significand of the floating point constant value. The first field, the second field, and the third field are combined to form the floating point constant value. The exponent value may include a bias, and a bias constant may be added to the exponent value to compensate for the bias. The third field may comprise the most significant bits of the significand. Optionally, the second field and the third field may be shifted by first and second shift values respectively before they are combined to form the floating point constant value.
