Patent ID: 7280113

Claim:
A method comprising: setting a plurality of operands in a system; setting a control register of the system to control a texture compositing operation with a circulation number of blend stages, to control a type of operation to be performed in each of a number of blend stages, and to control for each of the plurality of operands a selection, inversion, or replication operation; creating at least one texture map using YUV format; sending the texture map to a three dimensional graphic subsystem; selecting a first operand among the plurality of operands to be used for the texture compositing operation; performing the texture compositing operation, wherein the texture compositing operation includes counting the number of blend stages and performing color saturating only if the number of blend stages counted reaches the circulation number of blend stages, otherwise selecting a second operand among the plurality of operands for use in a subsequent blend stage without performing color saturating; sending a texture mapped polygon to a three dimensional graphic system; and outputting a result of the texture compositing operation from the three dimensional graphic subsystem to a display of the system.
