ABSTRACT:
A cellular logic operation processor for performing transformations, according to a controlled sequence, of the data points of a first matrix into a corresponding number of data points of a second matrix. The processor includes a plurality of operably connected digital storage devices for temporarily and sequentially storing each neighborhood of data points from a first matrix, wherein a neighborhood of data points is comprised of a central data point and its surrounding data points in a matrix. The processor also includes a plurality of taps wherein each tap is electrically connected to a digital storage device such that the tap electrically indicates the state of the data point stored in the digital storage device. A look-up table is also provided having stored therein a plurality of transformation values which are individually addressable in accordance with the combined states indicated by the taps. The transformation value addressed in response to the combined states indicated by the taps is output by the processor as the transformation value of the central data points of the currently stored neighborhood.
