| 20080209187 | Storing and processing SIMD saturation history flags and data size - A method and apparatus for calculation and storage of Single-Instruction-Multiple-Data (SIMD) saturation history information. A first coprocessor instruction has a first format identifying a saturation 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. | 08-28-2008 |
| 20080266310 | System and method for multiple color format spatial scaling - A method, apparatus, and system to scale a color image, the method including determining a color format of image data representative of the color image, the image data being in a pre-processed format and an unprocessed format; and performing a two-dimensional (2-D) image scaling operation on the image data, wherein a plurality of separable one-dimensional filters are applied to the image data to provide a scaled image of the color image and the image scaling operation is the same for the pre-processed formatted image data and the unprocessed formatted image data. | 10-30-2008 |
| 20080270768 | Method and apparatus for SIMD complex Arithmetic - Methods and apparatus for calculating Single-Instruction-Multiple-Data (SIMD) complex arithmetic. A coprocessor instruction has a format identifying a multiply and subtract instruction to generate real components for complex multiplication of first operand complex data and corresponding second operand complex data, a cross multiply and add instruction to generate imaginary components for complex multiplication of the first operand complex data and the corresponding second operand complex data, an add-subtract instruction to add real components of the first operand to imaginary components of the second operand and to subtract real components of the second operand from imaginary components of the first operand, and a subtract-add instruction to subtract the real components of the second operand from the imaginary components of the first operand and to add the real components of the first operand to the imaginary components of the second operand. | 10-30-2008 |
| 20090129695 | METHOD AND SYSTEM FOR NOISE MANAGEMENT FOR SPATIAL PROCESSING IN DIGITAL IMAGE/VIDEO CAPTURE SYSTEMS - A computer-implemented method for noise management in a digital image system measures noise levels of pixel data. The noise levels are adjusted with at least one of an intensity gain setting, a spatial gain setting, and a global gain setting to calculate noise adaptive thresholds for use during spatial processing of the pixel data. | 05-21-2009 |
| 20090300325 | DATA PROCESSING SYSTEM, APPARATUS AND METHOD FOR PERFORMING FRACTIONAL MULTIPLY OPERATIONS - A data processing system, apparatus and method for performing fractional multiply operations is disclosed. The system includes a memory that stores instructions for SIMD operations and a processing core. The processing core includes registers that store operands for the fractional multiply operations. A coprocessor included in the processing core performs the fractional multiply operations on the operands and stores the result in a destination register that is also included in the processing core. | 12-03-2009 |
| 20100215267 | Method and Apparatus for Spatial Noise Adaptive Filtering for Digital Image and Video Capture Systems - A system and method of adaptive edge detection and noise reduction in an image where edge information is detected for each color component of each pixel, whether sensed or synthesized. In some embodiments, the filter applied to a selected non-edge pixel may be determined by the ultimate size of a region around the selected pixel, where the size of the region may be increased if a count of the non-edge pixels in the region is less than a threshold value. | 08-26-2010 |
