In electronic computing systems, the binary-coded decimal (BCD) method encodes decimal numbers with each digit represented by its own four-bit binary sequence. The method allows easy conversion to decimal digits for printing or display, and also offers rapid decimal calculations. A proposed all-optical BCD adder uses a terahertz optical asymmetric demultiplexer (TOAD) to perform BCD addition in all-optical domain. © 2006 IEEE.
