  • Patent number: 8654133
    Abstract: Systems and methods are provided for processing data. The systems and methods include multiple processors that each couple to receive commands and data, where the commands and/or data correspond to frames of video that include multiple pixels. An interlink module is coupled to receive processed data corresponding to the frames from each of the processors. The interlink module divides a first frame into multiple frame portions by dividing pixels of the first frame using at least one balance point. The interlink module dynamically determines a position for the balance point that minimizes differences between the workload of the processors during processing of commands and/or data of one or more subsequent frames.

  • Patent number: 8427486
    Abstract: A multiprocessor system includes a plurality of special purpose processors that perform different portions of a related processing task. A set of commands that cause each of the processors to perform the portions of the related task are distributed, and the set of commands includes a predicated execution command that precedes other commands within the set of commands. It is determined whether commands subsequent to the predicated execution command are intended to be executed by a first processor or a second processor based on information in the predicated execution command and the set of commands includes all commands to be executed by each processor.

  • Patent number: 8054314
    Abstract: A system and method for applying non-homogeneous properties to multiple video processing units (VPUs) in a multiple VPU system are described. Respective VPUs in the system cooperate to produce a frame to be displayed. In various embodiments, data output by different VPUs in the system is combined, or merged, or composited to produce a frame to be displayed. In load balancing modes, each VPU in the system performs different tasks as part of rendering a same frame, and therefore typically executes different commands. In various embodiments, efficiency of the system is enhanced by forming a single command buffer for execution by all of the VPUs in the system even though each VPU may have a different set of commands to execute in the command buffer.

  • Patent number: 4831627
    Abstract: An energy generator (10) that converts matter in the form of a gas into an energy source. The generator functions by injecting a gas, such as hydrogen, into a confined chamber (12). The chamber includes an annular permanent magnet (30) and a rotating magnetic assembly (32) that includes a plurality of magnetic fins (36) that form a funnel shape. The combination of the magnets (30), (36) serves to accelerate and centrifugally confine and cause the gas molecules to collide with one another until they acquire sufficient energy to cause lasing.
