<p>A pipelined image processor generates an image of the information contained on first and second portions of a document includes a first pipe for processing information contained on the first portion of the document, and second pipe for processing information contained on the second portion of the document. The pipes receive the output from two camera assemblies which are used for generating an electrical signal in response to information contained on the document. An image digitizer generates digitized information from the electrical signals both pipes also include a resequencer for generating resequenced information from the digitized information, as well as an image processor for generating processed information from the resequenced information. The first and second pipes include a transposer/compressor assembly for generating transposed and compressed information from the processed information, and a compressed data buffer for storing the transposed and compressed information. During periods of inter-document time gaps, the diagnostic testing pattern is communicated to the resequencer, image processor, and transposer/compressor assemblies in the pipelined image processor. Each of these assemblies responds to the diagnostic testing pattern and the results are sent to a diagnostic transport interface which then determines faults associated therewith.</p> |
