Abstract
The image processing apparatus according to the present invention comprises: DMA control meanshaving image input/output processing means, an external memory, DMA setting holding means, address generating means, DRAM control means, DMA request generating means, and DMA request adjusting means; a processorincluding encoding/decoding processing means; and a DMA busas shown in FIG. In the image processing apparatus so constructed, a transfer data group which can be previously subjected to DMA scheduling is divided into burst transfer units, and the DMA request generating means periodically issues the DMA request in the burst transfer units and performs DMA of the transfer data which cannot be subjected to the DMA scheduling during the period that the DMA of the transfer data is not performed, thereby avoiding concentration of specific DMA.
