Abstract
Certain aspects relate to systems and techniques for compressing image data using pattern mode compression schemes. A pattern mode compression scheme can reduce the amount of data stored in a frame buffer to reduce power costs of an image display system. In some implementations, pattern mode compression can be suitable for compression of pixel blocks having a limited color palette with one or more pixels of a different foreground color, and a slope-enabled pattern compression can be suitable for compression of pixel blocks having a gradient. Input pixel values can be compared against a dynamically-populated, fixed size pattern entry database to determine whether pattern mode compression or slope-enabled pattern mode compression should be used to compress the image block.
