Abstract
Techniques for controlling access to a memory are provided. The techniques may include receiving and storing output pixel data in a buffer, providing the stored output pixel data to a display controller, receiving stored output pixel data from the buffer at the display controller, switching to a second operating mode state based at least on an amount of available data in the buffer being less than or equal to a threshold, identifying a portion of the image data stored in a memory device for use in generating output pixel data for an updated image, and, in response to operating in the second operating mode, generating the output pixel data without issuing a memory read command via an interconnect to retrieve the portion of the initial image while operating in the second operating mode, and providing the output pixel data to the buffer.
