Abstract
Methods and systems may include a compression module having logic to receive a pixel difference signal associated with an image, and conduct a compression of the pixel difference signal based on a value of the pixel difference signal. The logic can also generate a modified pixel difference signal based on the compression, wherein the compression may enable the image to be stored to dynamic random access memory (DRAM) in a compressed state.
