Graphics system and method for generating a blended image using content hints

A device operative to generate blended frames, with each blended frame composed of a plurality of image layers and each image layer composed of a plurality of regions, comprising:

• circuitry that includes a plurality of image producers to produce the image layers;
• a memory to store the image layers;
• and
• display hardware coupled to the circuitry and the memory, the display hardware operative to:
• retrieve a given image layer in a current frame from the memory;
• make a determination of whether to skip access to the memory for retrieving each region of each image layer in a next frame that is immediately after the current frame, based on at least content hints generated at the display hardware for the given image layer in the current frame;
• and
• access the memory for the next frame according to the determination.
