<P>PROBLEM TO BE SOLVED: To improve the utilization efficiency of a system bus and increase a processing speed while maintaining a configuration of the same circuit scale as that of a conventional apparatus in an apparatus for performing processing of rotating image data. <P>SOLUTION: To avoid single read access wasting the band width of the system bus, burst read access of quarter times substitutes for it. Further, the apparatus is configured so that 3/4 of the data required by a rotation circuit 104 may be supplied from an SRAM 102. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
