Optical on-the-fly conversion of a modified signed digit into two's complement binary number representation.
An optical carry-free technique is introduced for conversion of a modified signed digit (MSD) into two's complement binary number. Using a combination of optical polarizing beam splitters and retardation waveplates, the proposed device performs this conversion on the fly. The availability of this converter will lead to a large speed increase for various proposed optical parallel MSD arithmetic processors.
