    摘要: A computing platform may include heterogeneous processors (e.g., CPU and a GPU) to support sharing of virtual functions between such processors. In one embodiment, a CPU side vtable pointer used to access a shared object from the CPU 110 may be used to determine a GPU vtable if a GPU-side table exists. In other embodiment, a shared non-coherent region, which may not maintain data consistency, may be created within the shared virtual memory. The CPU and the GPU side data stored within the shared non-coherent region may have a same address as seen from the CPU and the GPU side. However, the contents of the CPU-side data may be different from that of GPU-side data as shared virtual memory may not maintain coherency during the run-time. In one embodiment, the vptr may be modified to point to the CPU vtable and GPU vtable stored in the shared virtual memory.

    摘要: The disclosed embodiment relates to system and method for separating background image from foreground text in one or more electronic pages. The one or more electronic pages are compared to check whether the background image in each of the one or more electronic pages are same. If it found that the one or more electronic pages have common background image, the common background image is subtracted from each of the one or more pages. The foreground text from each of the one or more electronic pages is recognized using an OCR. Finally, the recognized foreground text from each of the one or more electronic pages is consolidated in a file. The consolidated file can be printed or send to one or more recipients over an email.

    摘要: The material composition of a thin film formed on a substrate or covered by a cap layer that shares one or more elements with the thin film can be determined by combining characteristic material data, such as characteristic x-ray data, from a material composition analysis tool, such as an electron probe-based x-ray metrology (EPMA) operation, with thickness data and (optionally) possible material phases for the thin film. The thickness data and/or the material phase options can be used to determine, for example, the penetration depth of a probe e-beam of the EPMA tool. Based on the penetration depth and the thin film thickness, the characteristic x-ray data from the EPMA operation can be analyzed to determine the composition (e.g., phase or elemental composition) of the thin film. An EPMA tool can include ellipsometry capabilities for all-in-one thickness and composition determination.

    摘要: Methods and apparatus for RF handoff in a multi-frequency network. A method includes generating a handoff table that comprises RF channels of current and neighboring local operations infrastructures (LOIs) carrying the same content as a current RF channel; detecting a handoff event; disqualifying one or more of the RF channels from the handoff table based on disqualification criteria; selecting a selected RF channel from remaining RF channels in the handoff table that have not been disqualified; and performing a handoff from the current RF channel to the selected RF channel. Another method includes detecting a handoff event; identifying a start of a handoff time interval; determining if RSSI measurements are available at the start of the handoff time interval for RF channels carrying desired content; and performing a handoff to a selected RF channel having a greatest RSSI measurement.
