  • Using content type to select brightness in direct-lit backlight units
    Patent number: 11967291
    Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated by a backlight unit that includes an array of light-emitting diodes (LEDs). The backlight unit may determine the type of content in the image data. The backlight unit may decide to prioritize either mitigating halo or mitigating clipping based on the type of content. The determination of the type of content in the image data may be used to determine the brightness values for the LEDs in the LED array. If the content is determined to be a first type of content, at least one given LED in the LED array may have a different brightness value than if the content is determined to be a second, different type of content. Classifying content in the image data may be useful in optimizing visible artifacts such as visible halo and clipping.

  • Method and apparatus for MPI program optimization
    Patent number: 8312227
    Abstract: Machine readable media, methods, apparatus and system for MPI program optimization. In some embodiments, shared data may be retrieved from a message passing interface (MPI) program, wherein the shared data is sharable by a plurality of processes. Then, the shared data may be allocated to a shared memory, wherein the shared memory is accessible by the plurality of processes. A single copy of the shared data may be maintained in the shared data in a global buffer of the processes of the plurality of processes can read or write the single copy of the shared data from or to the shared memory.
