    摘要： A method, computer program product, and information handling system for generating loop code to execute on Single-Instruction Multiple-Datapath (SIMD) architectures, where the loop contains multiple non-stride-one memory accesses that operate over a contiguous stream of memory is disclosed. A preferred embodiment identifies groups of isomorphic statements within a loop body where the isomorphic statements operate over a contiguous stream of memory over the iteration of the loop. Those identified statements are then converted in to virtual-length vector operations. Next, the hardware's available vector length is used to determine a number of virtual-length vectors to aggregate into a single vector operation for each iteration of the loop. Finally, the aggregated, vectorized loop code is converted into SIMD operations.

    摘要： Metadata placeholders are used for distributed processing. The metadata placeholders are added to digital objects. The placeholders are filled with requests to perform certain downstream processing on the objects. The placeholders are at least partially empty so they can be filled in by nodes that perform the downstream processing.

    摘要： A method, computer program product, and information handling system for generating loop code to execute on Single-Instruction Multiple-Datapath (SIMD) architectures, where the loop operates on datatypes having different lengths, is disclosed. Further, a preferred embodiment of the present invention includes a novel technique to efficiently realign or shift arbitrary streams to an arbitrary offset, regardless whether the alignments or offsets are known at the compile time or not. This technique enables the application of advanced alignment optimizations to runtime alignment. This allows sequential loop code operating on datatypes of disparate length to be transformed (“simdized”) into optimized SIMD code through a fully automated process.

    摘要： A method is disclosed for identifying a selected portion of a video stream. A user interface is provided for designating a reference frame of a selected portion of a video stream. A processor is configured to compare the reference frame with other portions of the video stream to establish a similarity measure, process the similarity measure to identify a candidate region as a boundary of the selected portion of the video stream, and provide user access to the candidate region to designate the boundary for storage via the user interface.

    摘要： The disclosure is directed to a voice-controlled Bluetooth headset, which includes a receiver, a storage module, an offline voice recognition module, and a Bluetooth module. The offline voice recognition module is used to activate and recognize a preset voice when a preset activation password is received. The Bluetooth module is electrically connected to other modules, and is used for system control, Bluetooth transmission, and processing of instructions output by the preset voice recognition module and performs corresponding functions. With the above structure, the present disclosure can implement voice control of the Bluetooth headset according to a simple preset password, without manual operation, and is simple and convenient to use. The offline voice recognition module can achieve a preset voice control effect by setting a simple preset password, reducing the time required for the voice recognition device to recognize complex voice information, and the user's human-machine interaction experience is better, which further saves the cost required for voice recognition devices.
