Patent Images
1. A system to refresh a display, the system comprising:
- a memory to store images of an image frame in a plurality of memory pages, the image frame is divided into tiles representing two-dimensional regions of the image frame, each of the tiles is stored in one separate memory page;
a processor to perform drawing operations to generate the images for the image frame, the processor marking memory pages corresponding to regions of the image frame that have been updated while performing the drawing operations; and
a display controller in communication with the memory to access the image frame and to send only the marked memory pages of the image frame to the display to refresh the display.
