Abstract
A digital image differential pulse code modulation decompressor for simultaneously generating, during a cycle of operation of said decompressor, a decompressed value for a plurality of selected pixels located on a diagonal of an array of pixels. A storage stores an error value for each selected pixel to be processed during a cycle of operation of the decompressor. A processor simultaneously generates a decompressed value for each selected pixel where the decompressed value is derived from the error value for each selected pixel and a predicted value generated by the processor for each selected pixel. The predicted value is derived from a predictor which is at least a second order, two dimensional predictor. A digital image differential pulse code modulation compressor for simultaneously generating, during a cycle of operation of said compressor, a decompressed value and a encoded quantized error value for each of a plurality of selected pixels located on a diagonal of an array of pixels where the encoded quantized error values will be used in generating an image represented by said array of pixels.
