Abstract
Techniques are disclosed relating to storage techniques for fragment data. In some embodiments, one or more storage circuits are configured to store sample color data for processing by shader processors including a data structure that includes first and second elements configured to store color data for first and second colors, respectively. In some embodiments, control circuitry is configured to generate color state metadata to map samples in a region of pixels to colors in elements of the data structure, including to map multiple samples to the first element of the data structure. In some embodiments, control circuitry is configured to access the color state metadata to determine a mapped element of the data structure for a given sample and read the color data from the mapped element of the data structure. Disclosed techniques may improve, reduce or avoid duplication and thereby improve cache efficiency for accesses to color data.
