Abstract
A graphics system coalesces Z data and color data for a raster operations stage. The Z data and color data are stored in a memory aligned tile format. In one embodiment, rendering modes in which the tile does not have a data capacity corresponding to Z data or color data for a whole number of pixels have data for at least one pixel split across entries to improve packing efficiency. Rendering modes having a number of bits for Z data or color data that does not equal a power of two such as 24 bits, 48 bits, and 96 bits, may be implemented with a high packing efficiency in tile formats having a data capacity corresponding to a power of 2 bits.
