<p><P>PROBLEM TO BE SOLVED: To provide an MPEG decoder capable of achieving high processing performance. <P>SOLUTION: In the MPEG decoder, variable length decoding processing parts 36_0 and 36_1 perform variable length decoding processing per access unit in parallel. Intermediate data outputted from the variable length decoding processing parts 36_0 and 36_1 are stored in an intermediate data buffer 37, and a macro block line pointer indicating a data position of a macro block line where the intermediate data are stored in the intermediate data buffer 37 is recorded in a macro block line pointer table 38. Image decoding processing parts 39_0 and 39_1 refer to the macro block pointer table 38 to read out intermediate data of even macro block lines and odd macro block lines from the intermediate data buffer 37 respectively and perform image decoding processing of even macro block lines and odd macro block lines in parallel. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
