ABSTRACT:
The display controller includes a first memory storing image data and being accessed with a sequential access operation having a shorter access time than that of a random access operation, a second memory storing image data and consuming a less power than the first memory does at the time of the access operation and a data transfer control part performing an image data transfer control between the first memory and the second memory. The data transfer control part performs a transfer control to transfer the image data from the first memory to the second memory and transfer the image data written in the second memory after the image processing from the second memory to the first memory. The display controller supplies the image data in the first memory to a display driver.
