Abstract
Disclosed are methods and systems for tracking which data tiles have changed within an image frame. In an embodiment, each cell of a tile change list buffer may contain a frame number and updated when a tile is received from encoder. The frame number may be used as a base pointer for a particular frame buffer. When a frame is decoded, the contents of the tile change list buffer may be copied from the current tile change list buffer to the next buffer. This process may reduce memory traffic because the unchanged tile data does not have to be copied from frame to frame.
