Loading an internal frame buffer from an external frame buffer

A system including a first chip, a display controller and a copy device. The first chip includes a first memory. The display controller is configured to read a first frame from a second memory external to the first chip. The copy device is configured to copy the first frame from the second memory to the first memory while the display controller reads the first frame from the second memory. Subsequent to the copy device copying the first frame from the second memory to the first memory, the first frame is stored in both the first memory and the second memory.
