Abstract: Described herein is a data processing system comprising a memory device to store a multisample render target and a general-purpose graphics processor comprising a multisample antialiasing compressor and a multisample render cache. The multisample render target can store color data for a set of sample locations of each pixel in a set of pixels. The multisample antialiasing compressor can apply multisample antialiasing compression to color data generated for the set of sample locations of a first pixel in the set of pixels. The multisample render cache can store color data generated for the set of sample locations of the first pixel in the set of pixels. Color data evicted from the multisample render cache is stored to the multisample render target.

Abstract: Methods and apparatus relating to techniques for provision of color mapping for better compression ratio are described. In an embodiment, a plurality of bits are moved from all channels of a first Red Green Blue Alpha (RGBA) space to an alpha channel of a second RGBA space. The plurality of the bits are selected from higher order bits of the first RGBA space. Other embodiments are also disclosed and claimed.
