Abstract
Techniques described herein allow multi-pass writeback processing of graphical frames (such as those having a high or ultrahigh resolution) to reduce bandwidth for display operations by, for example, splitting an input stream for processing by separate graphical pipelines as two or more spatially segmented portions. After receiving a graphical frame for processing, the graphical frame is spatially segmented into multiple portions. Each of the multiple portions is provided to a respective graphical pipeline of a plurality of graphical pipelines for processing. Each processed portion of the graphical frame is written substantially simultaneously to a corresponding portion of a system memory.
