摘要 |
<p>An adder restores an image data by adding an output of a reverse DCT portion and an output of a predicted value calculating portion to output to a macro-block buffer. Data temporarily stored in the macro-block buffer is written in a predicting dynamic memory per a unit of data of one word consisted of 2 x 2 blocks of luminance component (Y), 1 x 2 blocks of Cr component and 1 x 2 blocks of Cb components, via a memory data bus. A prediction reference block of the preceding frame stored in the predicting dynamic memory is output to a reference block buffer via the memory data bus. A restored image data of the preceding frame in the predicting dynamic memory is output to a line buffer via the memory data bus. <IMAGE></p> |
