Abstract
A data processing system comprises a host processor and a graphics processor that renders frames to be output and writes those frames to a frame buffer. When a new frame is to be generated and written to the frame buffer, the host processor determines, for a set of plural sub-regions that the frame has been divided into, which of those sub-regions could have changed from the frame previously used for the frame bufferand generates information indicating which sub-regions should be rendered to generate the new frame on the basis of the determination The information indicating which sub-regions should be rendered to generate the frame is provided to the graphics processorand the graphics processor uses the provided sub-region information to render only the indicated sub-regions
