ABSTRACT:
The present invention provides a method and apparatus for enhancing the performance of video display devices by improving the utilization of memory resources used to process video data. In the system of the present invention, a display is configured to generate a visual image as a plurality of horizontal rows of pixels. In the present invention, the source data frame for said image is divided into row segments comprising a predetermined number of pixels from the entire horizontal row. A plurality of columns are constructed using individual pixel segments from the horizontal rows. The columns are further divided into a plurality of row segment blocks that are rotated and stored in destination memory to generate a rotated visual image.
