Abstract
A bit-matrix processor including a pair of optoelectronic matrices and a controller for causing the matrices to perform Boolean Matrix transforms to perform logical operations, wherein Boolean logical equivalents include logical AND to replace element-wise multiplication, and logical OR instead of summation. According to one embodiment, the processor includes an optical source matrix for receiving input binary data; a passive optical replicator for replicating a pattern on the optical source matrix and projecting it onto a Spatial Light Modulator (SLM); a database loading device for loading data onto the SLM thereby to perform logical AND with the optical source matrix data; an integrating device for integrating light from the SLM onto a photodiode matrix; and an output signal processing device.
