Abstract
Data transfer techniques include transferring display surface data from a memory subsystem into a stutter buffer at a first rate until the stutter buffer is substantially full. The memory interface and/or memory of the memory subsystem may then be placed into a suspend state until the stutter buffer is substantially empty. The display surface data is transferred from the stutter buffer to display logic at a second rate even when the memory subsystem is in a suspend state. The second rate, which is typically the rendering rate of the display, is substantially slower than the rate at which data is transferred into the stutter buffer.
