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 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 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： The claimed invention discloses system comprising a plurality of logical nodes comprised in a single or plurality of stages, with defined properties and resources associated with each node, for reducing compute resources, said system further comprising: at least a recirculating ring buffer holding only any one of a control information, input, and, or out data necessary to stream a temporary data between node and, or nodes in an execution graph, thereby reducing size of said recirculating ring buffer; said recirculating ring buffer being sufficiently reduced in size to reside in an on-chip cache, such that any one of the control information, input, and, or out data between node and, or nodes need not be stored in memory; wherein the control information further comprises a command related to invalidating any one of the input and, or out data held in a recirculating ring data buffer, clearing the buffer of tasked data; and wherein a producer is stalled from writing any more control information into a recirculating ring command buffer upon the buffer being full, preventing command buffer over-writing, and thereby reducing compute resources associated with a DRAM memory transaction.
