Abstract
A system and method for efficiently scheduling memory access requests from a display controller pipeline. The display controller monitors the amount of data in the line buffers in the internal pixel-processing pipelines. The display controller waits until the amount of data in a given line buffer has fallen below an amount equal to the pixel width of the region being rendered by the internal pixel-processing pipeline before issuing memory requests to the memory controller. When the memory controller is not processing received memory requests, the memory controller transitions to a low-power state.
