  • Publication number: 20230401420
    Abstract: A system receives a neural network model that includes asymmetric operations. Each asymmetric operation includes one or more fixed-point operands that are asymmetrically-quantized from corresponding floating-point operands. The system compiles a given asymmetric operation of the neural network model into a symmetric operation that includes a combined bias value. A compiler computes the combined bias value is a constant by merging at least zero points of input and output of the given asymmetric operation. The system then generates a symmetric neural network model including the symmetric operation for inference hardware to execute in fixed-point arithmetic.

  • Patent number: 10001856
    Abstract: Techniques pertaining to dynamic enablement, disablement and adjustment of offset of a virtual periodic timing control signal based on one or more predefined events are described. A method may determine whether a first predefined event is beginning. The method may also enable an offset of the virtual periodic timing control signal for synchronizing one or more first system modules in response to a determination that the first predefined event is beginning. The one or more first system modules may be configured to control one or more operations of one or more second system modules. The one or more second system modules may be configured to process one or more image frames. The method may further determine whether the first predefined event is ending. The method may additionally disable the offset in response to a determination that the first predefined event is ending.

  • Publication number: 20160366323
    Abstract: Methods and systems for improving images and video captured by a device is provided. The methods and systems may involve a virtual 3D model for a scene that is in view of a device's sensors. The virtual 3D model may be generated using the sensor information and be used to produce a 2D lighting image. The lighting image may be applied to a captured image of the scene to improve lighting of the captured image or video. A virtual light source may be implemented as part of the process, which if desired, can be moved, adjusted, or modified in the virtual 3D model to adjust the lighting image and consequently adjust alighted image or a final image.

  • Publication number: 20160055615
    Abstract: A technique, as well as select implementations thereof, pertaining to smart frequency boost for graphics-processing hardware is described. A method may involve monitoring a queue of a plurality of graphics-related processes pending to be executed by a graphics-processing hardware to determine whether one or more predetermined conditions of the graphics-related processes in the queue are met. The one or more predetermined conditions may include an accumulation condition of the graphics-related processes in the queue. The method may also involve dynamically adjusting at least one operating parameter of the graphics-processing hardware in response to a determination that each of the one or more predetermined conditions of the graphics-related processes in the queue is met.

  • Patent number: 7746201
    Abstract: A portable electronic device includes a cover section (54), a body section (52), a magnet (60) and a hall sensor (70). The cover section has a printed circuit board secured therein. The body section has a connecting portion, and the body section is rotatably connected to the cover section with the connecting portion. The magnet is secured in the connecting portion, and the hall sensor is electrically attached to the printed circuit board. The magnet acts on the hall sensor according to relative rotation between the cover section and the body section, thereby switching the portable electronic device to a work mode when the cover section is opened away from the body section or a power save mode when the cover section is closed to the body section.
