[4] Code Morphing software transforms x86 binary code into individual instructions, called atoms, for the Crusoe processors. The compiler within the new software then looks for atoms that can be executed together and groups them into very long instruction words called molecules. Molecules may contain two or four atoms. In cases where an atom is to be executed alone, or only three atoms are to be executed together, the second or fourth position is filled by a no-operation instruction.
