    摘要： The present invention provides a stream processing apparatus capable of improving the processing performance in the case of continuously processing a plurality of data streams. A control stream, different from a data stream, is prepared, and a program and a parameter are updated in advance in accordance with the control stream. Double buffer areas are prepared in a memory of the stream processing apparatus into which the program and the parameter are stored. The location of the data stream to be input is written in the control stream, and buffers for reading the data stream are multiplexed so as to read in advance the top portion of the data stream to be processed next.

    摘要： The variable length decoder has a memory device including a plurality of lookup tables, and sequentially decodes codewords of variable-length codes using the memory device. The decoded values corresponding to the codewords and control information pieces are stored in the lookup tables. In decoding one codeword, one lookup table is selected from among the plurality of lookup tables. In the decode, one decoded value corresponding to the one codeword, and a control information piece for selecting a next lookup table depending on the decoded value and used for a next decode are produced from the selected lookup table in response to the one codeword in parallel.

The functional block includes two moving picture processing units, and a memory unit that stores therein data related to the results of processing of first plural macroblocks arranged within one row of one picture by the first moving picture processing unit. Data related to the results of processing of plural adjacent macroblocks, which are selected from the data stored in the memory unit, are transferred to the second moving picture processing unit. The second moving picture processing unit performs processing of one macroblock of second plural macroblocks arranged in the following row, using the transferred data.

    摘要： The present invention provides a technology that is implemented in a motion compensation image coding device or a coding method and intended to code motion picture data in real time by performing a decreased number of arithmetic operations so as to determine a motion vector. In motion compensation image coding, macroblocks and sub-blocks into which each of the macroblocks is divided are searched for a motion vector with integer pixel precision. Based on the results of the search, a shape of a block that should be searched for a motion vector with decimal pixel precision is determined as a shape mode. The block of the shape mode is searched for a motion vector with decimal pixel precision, whereby a motion vector needed to produce predictive image data is determined.
