Patent ID: 7286717

Claim:
An image data processing device comprising: an image processor inputting/outputting a predetermined number n of multi-bit image data items arranged serially in time series, where n is a number larger than one, a number of processor elements, which number is larger than the number n, processing the image data items inputted by an interface, simultaneously in parallel and outputting the processed image data items to the interface, and a processor control unit controlling operation of each of the interface and the number of processor elements; an image port inputting/outputting at least one series of image data items arranged serially in time series; and a buffer memory device including at least one memory usable as a line memory for image data so as to store said series of said image data items, wherein said buffer memory device includes a memory controller having a plurality of functions including a function of dividing each of said image data items of said series inputted by the image port successively in time series, into n series of image data items and supplying the image data items of the n series to the image processor simultaneously in parallel, a function of extracting each of the image data items successively from the n series of the image data items outputted by the image processor simultaneously in parallel, so as to synthesize said n series of said image data items into the series of the image data items, a function of supplying each of said image data items of said series inputted by the image port successively in time series, to the image processor simultaneously in parallel, and a function of supplying each of the n series of the image data items outputted by the image processor simultaneously in parallel, to the image port so as to output the n series of the image data items from the image port simultaneously in parallel.
