Abstract:
A system includes internal memory and external memory. A display controller reads a frame from the external memory. At least one of a processor and a graphics chip copies the frame from the external memory to the internal memory while the frame is read from the external memory by the display controller. After the frame is copied to the internal memory, the frame is stored in both the internal memory and the external memory.
