  • Publication number: 20090160867
    Abstract: Embodiments directed to an autonomous graphics processing unit (GPU) scheduler for a graphics processing system are described. Embodiments include an execution structure for a host CPU and GPU in a computing system that allows the GPU to execute command threads in multiple contexts in a dynamic rather than fixed order based on decisions made by the GPU. This eliminates a significant amount of CPU processing overhead required to schedule GPU command execution order, and allows the GPU to execute commands in an order that is optimized for particular operating conditions. The context list includes parameters that specify task priority and resource requirements for each context. The GPU includes a scheduler component that determines the availability of system resources and directs execution of commands to the appropriate system resources, and in accordance with the priority defined by the context list.

  • Publication number: 20090160865
    Abstract: Embodiments of the invention as described herein provide a solution to the problems of conventional methods as stated above. In the following description, various examples are given for illustration, but none are intended to be limiting. Embodiments include a frame processor module in a graphics processing system that examines the intra-coded and inter-coded frames in an encoded video stream and initiates migration of decoding and rendering functions to a second graphics processor from a first graphics processor based on the location of intra-coded frames in a video stream and the composition of intermediate inter-coded frames.

  • Publication number: 20090016430
    Abstract: Embodiments of a software video encoder with GPU acceleration include a software encoder that partitions video processing tasks and assigns them to both a graphics processing unit (GPU) and a central processing unit (CPU). The partitioning and assigning is configurable for operation in different modes. The modes include a mode in which the total time for video processing (such as when transcoding a large existing file) is reduced, a mode in which less CPU cycles are consumed, thus freeing the CPU for other work, ad mode in which the latency of processing (e.g., for video conferencing) is reduced, and a mode in which information from a game or other real-time activity being displayed on the screen is encoded.

  • Publication number: 20080278595
    Abstract: Embodiments of the video data capture and stream method comprise intercepting a flip function call comprising a call by the video application to flip frames between a display and a buffer, grabbing a copy of the current frame that would normally be processed by a central processing unit (CPU), placing the copy in a queue for processing by a graphics processing unit (GPU), wherein processing by the GPU is significantly faster than processing by the CPU.

  • Patent number: 7153364
    Abstract: The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.

  • Patent number: 7062399
    Abstract: According to an example embodiment of the present invention a semiconductor die having a resistive electrical connection is analyzed. Heat is directed to the die as the die is undergoing a state-changing operation to cause a failure due to suspect circuitry. The die is monitored, and a circuit path that electrically changes in response to the heat is detected and used to detect that a particular portion therein of the circuit is resistive. In this manner, the detection and localization of a semiconductor die defect that includes a resistive portion of a circuit path is enhanced.

  • Patent number: 6878895
    Abstract: A reticle sorter and a semiconductor fabrication facility employing one or more reticle sorters is provided. The reticle sorter(s) generally lies between a reticle storage system and a group of one or more photolithography exposure tools (e.g., steppers) and is configured for sorting reticles in one or more cassettes. The use of the reticle sorter provides sorting functionality apart from the reticle storage system and typically closer to the group of photolithography steppers with which it is associated. This can, for example, significantly increase the throughput of semiconductor wafers through the associated photolithography exposure tools as well as in the semiconductor fabrication plant as a whole.

  • Patent number: 6836132
    Abstract: A semiconductor device is analyzed and manufactured using a heat-exchange probe. According to an example embodiment of the present invention, a heat-exchange probe is controlled to exchange heat to a portion of a semiconductor device using sub-micron resolution. In one implementation, sub-micron resolution is achieved using a navigational arrangement, such as microscope, adapted to direct light to within about one micron of a target circuit portion on a plane of the device. In another implementation, a physical heat probe tip (e.g., a metal probe having about a one micron diameter probe tip) is navigated to a selected portion of the device using sub-micron navigational resolution. In each of these implementations, as well as others, the heat exchange is preponderantly confined to within about a one micron radius of a target portion of circuitry on lateral plane of the device.

  • Patent number: 6795357
    Abstract: A method of detecting a charge stored on a charge storage region of a first dual bit dielectric memory cell within an array of dual bit dielectric memory cells comprises applying a source voltage to a first bit line that is the source of the selected memory cell and applying a drain voltage to a second bit line that forms a drain junction with the channel region. The source voltage may be a small positive voltage and the drain voltage may be greater than the source voltage. A read voltage is applied to a selected one of the word lines that forms a gate over the charge storage region and a bias voltage is applied to non-selected word lines in the array. The bias voltage may be a negative voltage.
