ABSTRACT:
Two-dimensional digital computers and computer devices operate in parallel on rectangular arrays of digital radiant energy optical signal elements which are arranged in ordered rows and columns. Logic gate devices receive two input arrays and provide an output array having digital states dependent only on the digital states of the signal elements of the two input arrays at corresponding row and column positions. The logic devices include an array of photoconductors responsive to at least one of the input arrays for either selectively accelerating electrons to a phosphor output surface, applying potentials to an electroluminescent output layer, exciting an array of discrete radiant energy sources, or exciting a liquid crystal to influence crystal transparency or reflectivity. An image combiner/duplicator serves as an interface device for either converting two spaced apart input arrays to a combined input array or for converting an input array to two spaced apart output arrays. Interconnecting devices provide an output array having signal element digital states dependent on the states of non-corresponding input signal elements. Such devices include: a slider for translating the output array with respect to the input array; a twister for rotating the output array by a multiple of 90.degree.; an interchanger of rows and columns; an inverter of row or column element order; a magnifier responsive to a subarray of an input array; a spiller device responsive to the state of a single input element; a contractor device having an output signal element responsive to a digital 1 of any input element; a sweeper device for producing redundant rows or columns corresponding to a single input row or column. Memory devices utilizing the gates in conjunction with regenerative feedback also serve to threshold analog images. An A/D converter system converts an analog input image into bit planes. An array computer system organization includes array mask gating for performing different operations simultaneously on different image portions.
