ABSTRACT:
The present invention is directed to an image processing apparatus for achieving an increase of capacity and an improvement in processing capability without causing a drop in performance and an increase in cost. The apparatus includes built-in memory, external memory, and a memory interface (I/F) circuit. The external memory is divided into a plurality of blocks that store predetermined data. The built in memory is accommodated on the semiconductor chip and is divided into blocks having the same capacity as a divided block of the external memory. The memory I/F circuit displaces data stored in the built-in memory with data stored in the external memory based on a displacement command.
