Abstract:
1. A graphics processor comprising: logic grouping binary data of a block of pixels into a plurality of bit-planes, each bit-plane corresponding to a different bit position in the binary data of the block of pixels and including a bit value from each pixel in the block at that corresponding bit position; an encoding, associated with the block of pixels, that represents which one or more of the bit-planes is a constant-value bit-plane having binary data comprised of a same bit value from every pixel in the block and which one or more of the bit-planes is a mixed-value bit-plane, wherein the encoding includes: wherein the bit value is established as irrelevant in response to the indicator mask failing to identify that the bit-plane is a constant-value bit-plane; and logic accessing memory storing the block of pixels to process the binary data of each mixed-value bit-plane and accessing memory storing the encoding to process the binary data of each constant-value bit-plane when a processing operation is performed on the block of pixels.
