  • Patent number: 10185659
    Abstract: A system is provided for allocating memory for data of a program for execution by a computer system with a multi-tier memory that includes LBM and HBM. The system accesses a data structure map that maps data structures of the program to the memory addresses within an address space of the program to which the data structures are initially allocated. The system executes the program to collect statistics relating to memory requests and memory bandwidth utilization of the program. The system determines an extent to which each data structure is used by a high memory utilization portion of the program based on the data structure map and the collected statistics. The system generates a memory allocation plan that favors allocating data structures in HBM based on the extent to which the data structures are used by a high memory utilization portion of the program.

  • Patent number: 10134349
    Abstract: Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels and control circuitry for operating the display. In some scenarios, interference signals from other components of the electronic device or additional external devices can couple to the control circuitry for the display and cause distortions in displayed data. Display frames may be displayed by an electronic device display with a varying phase. The varying phase display frames may each include a distortion pattern that also varies from frame to frame due to the varying phase. The varying distortion patterns may average out or visibly cancel when viewed by a user such that no visible artifact of the interference signal is seen by the user. The varying phase can be actively tuned to the interference signal if desired.

    Abstract: An electronic handwriting device (e.g., a tablet device or smart phone) detects a first touch and a second touch (e.g., from a pen device) on or near a writing surface of the electronic handwriting device. The electronic handwriting device determines whether the first touch is a dropped touch. Upon determining that the first touch is a dropped touch, the electronic handwriting device applies data filtering to data that is potentially associated with the second touch. After the data filtering step, the electronic handwriting device determines whether to generate a stitching segment between a first line segment associated with the dropped touch and a second line segment associated with the second touch. The determination of whether to generate the stitching segment also may be based on other factors, such as the proximity of the second touch to the dropped touch.

  • Patent number: 9613451
    Abstract: One embodiment of the present invention sets forth a technique for rendering anti-aliased paths by first generating an alpha buffer representing coverage data. To generate the alpha buffer, jittered versions of the rendered path are rendered and corresponding stencil buffers indicating sub-pixel samples of the path that should be covered are generated. After each stencil buffer is generated, the jittered path is rasterized to convert the sub-pixel coverage into coverage weights that are stored in the alpha component of a frame buffer. As each jittered path is rasterized, the coverage weights are accumulated. Finally, geometry representing the union of the jittered versions of the path is rendered to shade pixels based on the accumulated coverage weights. The anti-aliased rendered paths may be filled or stroked without tessellating the paths.

  • Patent number: 9449090
    Abstract: A system, method and computer program utilize a distance associative hashing algorithmic means to provide a highly efficient means to rapidly address a large database. The indexing means can be readily subdivided into a plurality of independently-addressable segments where each such segment can address a portion of related data of the database where the sub-divided indexes of said portions reside entirely in the main memory of each of a multiplicity of server means. The resulting cluster of server means, each hosting an addressable sector of a larger database of searchable audio or video information, provides a significant improvement in the latency and scalability of an Automatic Content Recognition system, among other uses.

  • Patent number: 9443285
    Abstract: A method for replacing image data in a destination region that is divided into sub-pieces along one or more cutting paths, which start and end at two different points on the border, and finding replacement data for the sub-pieces. The cutting paths may be determined as a function of the type of image structured at the start and the end points. The cutting paths may also be determined as a function of the area of the sub-pieces and the lengths of the cutting paths. Optionally, the destination region may be determined by a spot detection algorithm. Further optionally, the spot detection algorithm may comprise calculation of a high pass filter, or detection of areas of luminosity and border-to-volume ratios. A method for moving an image element within an image is also provided.

    Abstract: A system, method, and computer program product are provided for accessing multi-sample surfaces. A multi-sample store instruction that specifies data for a single sample of a multi-sample pixel and a sample mask is received and the data for the single sample is stored to each sample of the multi-sample pixel that is enabled according to the sample mask. A multi-sample load instruction that specifies a multi-sample pixel is received, and, in response to executing the multi-sample load instruction, data for one sample of the multi-sample pixel is received. A determination is made that the data for the one sample of the multi-sample pixel represents multi-sample pixel data for at least one additional sample of the multi-sample pixel.

  • Patent number: 9369610
    Abstract: In order to suitably perform image processing for enhancing edge reproducibility on an image, an image processing apparatus, determines whether or not a pixel of interest in an input image is a pixel configuring an edge, and determines whether or not the pixel of interest in the input image is a pixel configuring a semi-transparent object. In addition, the apparatus performs image processing for enhancing edge reproducibility for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is not a pixel configuring a semi-transparent object. On the other hand, the apparatus inhibits execution of the image processing for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is a pixel configuring a semi-transparent object.

  • Patent number: 9336561
    Abstract: A color buffer cache may be implemented in a way that reduces memory bandwidth. In one embodiment this may be done by determining whether a corresponding tile being rendered is completely inside a triangle. If so, the cache lines that correspond to this tile may be marked as “less useful”. As a result of being marked as less useful, those cache lines may be replaced before other cache lines in one embodiment. Thus a color buffer cache is used for those tiles that overlap with at least one triangle edge. The use of such a color buffer cache scheme may be more efficient and therefore may reduce memory bandwidth in some embodiments.
