This manuscript represents the second paper in a series of publications describing alternative combinatorial logic based optical computing architectures. Within the first paper titled "Combinatorial Logic Based Optical Computing," justification for combinatorial logic is initially debated through the coupled use of extensive optical interconnects with the natural "and-or-invert" capability of most every optical system.1 This is followed by a simple example of an optical "text" processor, a word and phrase comparitor which can be used for massive text look-up and search. This demonstrates the ability to design a wide range of digital optical architectures capable of performing numerous, if not myriad, sets of digital functions other than mathmatical. The original paper continues to describe a digital optical full adder enhanced by the full global broadcast capability of optics. Finally, a 2 x 2 bit systolic multiplier is described for matrix processing where the limitations of the DMAC algorithm are finally overcome.2-5 The output is thus a full 4 bit binary weighted result.
