Abstract
An image processing device improves processing performance at low cost. The image processing device is provided with a memory controller that divides up and assigns banks accessed by a video inputter, a drawer, and a video outputter to multiple frame memories. The image processing device arbitrates access requests from master units, such as the video inputter, the drawer, and the video outputter, and controls data transmission so that the multiple master units can access both the frame memories in parallel.
