摘要： A circuit for blending video signals and subpicture signals is provided. The circuit includes a palette to output at least one subpicture value based on a palette index. The circuit also includes an alpha-blend unit coupled to the subpicture palette to blend a set of luminance values of a video signal with a set of luminance values of a subpicture signal in one pass and to blend a set of chrominance values of a video signal with a set of chrominance values of the subpicture signal in a separate pass, the luminance and chrominance values are provided to the alpha-blend unit in a planar format. The video signals may be provided and blended in a YUV 4:2:0 format. In addition, a single dual-purpose palette can be used for both texturing and alpha-blending.

摘要： A machine readable storage media containing executable program instructions which when executed cause a digital processing system to set a plurality of operands and operators. A plurality of texture maps are sent to a processor for texture compositing. Operands are selected for a texture operation. A first logic is used wherein if the circulation of blend stages is equal to a number of blend stages, then a color saturation is performed, and a second logic that if the circulation number of blend stages does not equal the number of blend stages then at least one operand is selected for another texture compositing operation.

摘要： A method and circuit for determining the address of texture maps in memory, when only the base address of the primary texture map is known. The various maps associated with a given texture are sized and stored in a manner that allows any texel in any of the maps to be located based on the map number and the base address of the primary map. A circuit is provided that determines the necessary addresses with minimal calculations.

摘要： A texture data reading apparatus includes a cache memory including a plurality of read ports and a plurality of regions to store pixel texture data. An address comparator includes a plurality of input ports to receive incoming pixels, wherein the address comparator compares the memory addresses associated with the incoming pixels to determine which regions of cache memory are accessed. A cache lookup device accesses new texture data from the cache memory for the incoming pixels in the same clock cycle in response to the number of memory regions accessed being less than or equal to the number of cache memory read ports.
