摘要： According to some embodiments, a Single-Instruction/Multiple-Data averaging operation is presented. The averaging operation averages multiple sets of data elements, for example, two data elements each from a first source and a second source, producing a set of averages. In at least one embodiment, in a first adder stage, a first plurality of data elements are added to a second plurality of data elements, generating a plurality of intermediate results. In a second adder stage, multiple different combinations of the plurality of intermediate results are added together, generating a plurality of sum results. The two least significant bits of each sum result are discarded.

摘要： Apparatus, systems and methods for providing display bandwidth and power reduction are disclosed. In one implementation, a display controller may treat overlay layer image data as non-transparent and to fetch only base layer image data that will not be overlain. In another implementation, a display controller may auto detect when an overlay layer is sized to fill the display screen and supply only overlay layer image data to a display. In another implementation, a display controller may substitute a constant color value for base layer image data and combine that constant color value with overlay layer data when providing image data to a display.

摘要： A method and apparatus for calculation and storage of Single-Instruction-Multiple-Data (SIMD) saturation history information pursuant to instruction execution. A first coprocessor instruction has a first format identifying a saturating operation, a first source having packed data elements and a second source having packed data elements. The saturating operation is executed on the packed data elements of the first and second sources. Saturation flags are stored in the Wireless Coprocessor Saturation Status Flag (wCSSF) register to indicate if a result of the saturating operation saturated. A second coprocessor instruction has a second format identifying a saturation history processing operation and a saturation data size. An operand for the processing operation is determined based on the saturation data size, and the processing operation is executed on the saturation flags and the operand for the saturation data size. Condition code flags are stored in a status register to indicate the result of processing operation.

摘要： According to some embodiments, a Single-Instruction/Multiple-Data (SIMD) averaging instruction is used to process pixels of image data. The averaging instruction generates a set of four-pixel averages, where each average is generated from two pixels in a first source register and two pixels in a second source register. The first source register contains a plurality of pixels from a first row of pixels and the second source register contains a plurality of pixels from a second row. In one embodiment, the first and second rows are adjacent rows in an image and the averaging instruction is used, for example, to down-scale an image, perform color conversion, and the like. In another embodiment, the first and second rows are from different images and the averaging instruction is used, for example, in motion estimation for video encoding, in motion compensation for video decoding, and the like.
