<p><P>PROBLEM TO BE SOLVED: To speedily perform access processing with respect to a DRAM in MPEG processing. <P>SOLUTION: A two-dimensional image is input in order of raster, and these image data are stored in a 16-bit SDRAM performing changeovers between a bank 0 and a bank 1. Concretely, the data are stored performing changeovers between the bank 0 and the bank 1 by every 8 pixel. In this case, data in the direction of the row of the two-dimensional image are stored in the same bank. When a 32-bit SDRAM is used, data are stored performing changeovers between the bank 0 and the bank 1 by every 16 pixel. In this case, storage is performed concerning the data in the row direction of the two-dimansional data so that the bank 0 and the bank 1 alternate. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
