Abstract : Cellular machines are two dimensional arrays of rather primitive processing elements (PE-s) that are controlled by the internal state of their neighborhood PE-s and (usually) by some external instruction stream in a SIMD style. Such machines offer high computational speed for a useful class of problems, particulary in image processing. While some cellular machines were implemented in silicon, newer versions with enhanced connectivity, such as the cellular hypercube, are probably too complex for electronics. Furthermore, the 'almost-shift-invariant' geometry of cellular machine interconnections is a good match to optical convolution, which is easy to carry out. In this work we discuss an alternative method for implementing optical cellular machines.
