  • Publication number: 20140375658
    Abstract: An apparatus and method for processor core to graphics processor scheduling and execution is disclosed. In one embodiment, an apparatus includes a general purpose processor configured to execute instructions from a first instruction set and a graphic processing unit (GPU) configured to execute instructions from a second instruction set. The apparatus also includes a microcode unit configured to store microcode instructions that, when executed by the general purpose processor core, generate translated instructions, wherein the translated instructions are generated by translating selected instructions from the first instruction set translated into instructions of the second instruction set. The general purpose processor is configured to, responsive to performing a translation, pass the translated instructions to the GPU. The GPU is configured to execute the translated instructions and pass corresponding results back to the general purpose processor.

  • Patent number: 8910409
    Abstract: A method of producing autofrettage in a tubular component provides a tubular workpiece having an inner diameter and an outer diameter and provides at least two rollers having a displacement from one another in an axial direction with respect to the workpiece. The method places the workpiece on a mandrel such that the inner diameter is adjacent to the mandrel. The method also compresses the outer diameter of the workpiece with the rollers at a temperature below a recrystallization temperature of the workpiece using a combination of axial and radial forces so that the mandrel contacts the inner diameter and imparts a compressive hoop stress to the inner diameter of the workpiece.

  • Patent number: 8909961
    Abstract: Briefly, a method and apparatus adjusts the power consumption level of an integrated circuit by dynamically scaling the clock frequency based on the real-time determined power consumption level. In one example, the method and apparatus changes an actual clock frequency of the integrated circuit to an effective clock frequency based on the maximum clock frequency and the difference between the threshold power consumption level and the actual power consumption level of the integrated circuit in the previous sampling interval. In one example, an effective clock frequency of the integrated circuit in the current sampling interval is determined. In one example, the difference between the maximum and effective clock frequencies in the current sampling interval is proportional to the difference between the threshold and actual power consumption levels in the previous sampling interval. The actual clock frequency of the integrated circuit is changed to the determined effective clock frequency.

  • Patent number: 8907958
    Abstract: A method and apparatus for providing rendering of subsections of screen space receives render commands associated with different screen subsections, such as from a command buffer populated by a coprocessor, and determines which screen section is currently being rendered by a rendering engine, or stated another way, which screen section the host processor wishes to have rendered, and evaluates screen subsection data that is associated with a received rendering command. The screen subsection data identifies a screen subsection for which the command refers. The method includes executing the command if it is determined that the command refers to a current screen section being rendered.

  • Patent number: 8909182
    Abstract: A narrow band, tunable antenna uses a series of small inductors wired in series to produce different resonant frequencies from a single antenna across a wide frequency spectrum. Radio Frequency (RF) switches are positioned in parallel with the inductors and are capable of shunting a selected inductor out of the antenna circuit thereby changing the electrical length of the antenna and consequently, the resonant frequency. The RF switch control circuitry is isolated from the RF current in the antenna.

  • Patent number: 8891583
    Abstract: An apparatus for casting metals by a nucleated casting technique to create a preform, the apparatus including a mold having a base and a side wall where the base can be moved relative to the side wall to withdraw the preform as it is being created. In various circumstances, portions of a droplet spray created by an atomizing nozzle, i.e., overspray, may accumulate on a top surface of the side wall and prevent or inhibit the preform from being moved relative to the side wall. The atomizing nozzle can be oriented such that the droplet spray passes over the top of the side wall to remelt and remove at least a portion of the overspray that has accumulated thereon. The mold can be rotated such that the overspray formed on a region of or on the entire perimeter of the top surface can pass through the droplet spray and can be removed from the side wall.

  • Patent number: 8879680
    Abstract: A transmitting interconnect interface inserts clock mismatch compensation symbols into a transmitted data stream so as to allow the receiving interconnect interface to compensate for clock frequency mismatch between transmit-side and receive-side clocks. The transmitting interconnect interface adjusts the rate of insertion of these symbols based on a determination of the clock frequency mismatch. The transmitting interconnect interface can incrementally adjust the insertion rate to change substantially proportionally with changes in the clock frequency mismatch. Alternatively, the transmitting interconnect interface can set the insertion rate to one of two levels. By adapting the insertion rate to the current measured clock frequency mismatch, the bandwidth penalty incurred by transmitting clock mismatch compensation symbols in excess of that necessary to permit receiver clock tolerance compensation can be reduced, thereby permitting more transmit bandwidth to be used for transmitting data.

  • Publication number: 20140321533
    Abstract: Apparatuses, computer readable mediums, and methods of encoding video are disclosed. A video comprising a plurality of frames is encoded. The method may determine whether to encode a frame as an interframe (I frame) or a predicted frame (P frame). An I frame may be encoded with a quantization parameter (QP), which may be determined for the I frame. A P frame may be encoded with a QP limited to vary between a lower QP and an upper QP. After encoding N P frames, QP may be adjusted, where N is a fixed or dynamically adjusted number of frames. If a number of bits used to encode the N P frames exceeds a first budget threshold then the value of QP may be raised, and if the number of bits used to encode the N P frames is below a second budget threshold then the value of QP may be lowered.
