Abstract:
A high precision floating point emulator and associated method for emulating subject program code on a target machine where the subject machine base operands possess a different precision than the target machine. The high precision floating point emulator is provided for the emulation of subject program code instructions having a higher precision than that supported by the target machine architecture by utilizing intermediate calculations having values with a higher precision than that supported by the target machine.
