A decoding device improves a cache hit rate in a decoding process of compressed encoded image data. The decoding device, before the decoding process, generates a sort table for each reference picture for a plurality of MPEG data streams included in a GOP and having a frame type of P- or B-picture. The decoding device, by using the generated sort table, selects a group of pictures composed of a plurality of decoding target macro blocks that refer to the same reference macro block. The decoding device obtains, from the reference picture, four macro blocks including the same reference macro block referred to by the selected picture group, and stores the four macro blocks into the cache memory. The decoding device sequentially decodes each decoding target macro block included in the selected picture group, by using the four macro blocks stored in the cache memory.

An apparatus for parallel image generation has four geometric data buffers for storing four partial geometric data, respectively, and four image generators connected respectively to the four geometric data buffers. Each image generator generates a partial image data for every pixel in a frame. Further provided are four image mergers connected respectively to the four image generators. The four image mergers are also connected in series. An initial image generator for generating a background image is connected to the first image merger for merging the background image data and the partial image data from the first image generator. Each of the second to fourth image merger merges an output merged data from the previous image merger and the partial image data from the corresponding image generator. A timing control is connected to the four image mergers for controlling the merging timing in such a manner that the image merger carries out the merging operation of a pixel after the previous image merger has carried out the merging operation of the same pixel.
