Abstract
PURPOSE:To attain high speed by outputting the result of reduction processing in parallel toward the LSB and packing the result into a word with a predetermined bit width while referencing the value of a bit counter. CONSTITUTION:A reduction bit instruction string and an image referenced in parallel and reduced by parallel reduction devices 3, 4 to reduce the image and the result is outputted toward the LSB. The result is packed into a word data with a predetermined bit width by pack circuits 7, 9 by using bit counters 5, 6 counting number of 1s in the reduction bit instruction string in parallel and adders 8, 10 summing the outputs. Thus, high speed of a multiple of W (W is the parallel data width) is attained in comparison with a conventional image reduction bit instruction string serial reference.
