A determination is made as to whether selected data in the second area of the frame buffer is required during the generation of an upcoming display line. The selected data is read from the second area when such data from the second area of the frame buffer is required for generation of the upcoming display line. A refresh is initiated of at least a portion of the second area when data from the second area is not required for the generation of the upcoming display line and a time for refresh of the second area has been reached.</p> |
