ABSTRACT:
An image processing device which processes a portion of the decompression process including a lot of comparatively complex operations like an inverse discrete cosine transform by software with using a high-performance, general-purpose processor capable of parallel processing, and the other portion of the decompression process which is comparatively simple but requires frequent access to a memory, e.g., when other frame data is to be read out for processing of encoded interframe predictive image data, or is comparatively simple but substantially hard to process in parallel, e.g., when variable length coded pixel values are to be decoded, by hardware with the use of a specialized peripheral circuit.
