    摘要： A method and circuit for generating a signal to synchronize DQ data transfer in memory interface design is presented. The presented method includes receiving a strobe signal having a preamble period before and post-amble period after data transfer burst synchronization signal edge transitions, determining a timing location of the strobe signal preamble period, determining a timing location of the strobe signal post-amble period, and generating a clean strobe signal that tracks the data transfer burst synchronization edge transitions of the strobe signal after the strobe signal preamble begins and before the strobe signal post-amble ends based on the respective determined timing locations of the strobe signal preamble and post-amble periods. In this manner, DQ data transfer may be synchronized according to the burst synchronization signal edge transitions and errors caused by strobe signal level jitter during the preamble and post-amble periods are reduced.

    摘要： A system and method for self-configuring multi-type and multi-location result aggregation for large cross-platforms is presented. An enterprise tier component includes a request manager that receives query requests from a distribution tier component over a request path. The request manager retrieves one or more data thresholds and compares the data query's result to the data thresholds. When the data query result is less than the data thresholds, the request manager sends the data query result to the distribution manager over the request path. However, when the data query result exceed one of the data thresholds, the request manager stores the data query result in a temporary storage area and sends metadata, which includes the temporary storage area location, to the distribution tier component over the request path. In turn, the distribution tier component retrieves the data query result directly from the temporary storage area over a dedicated data path.

    摘要： The present invention provides a compound powder for making magnetic powder cores, a kind of magnetic powder core, and a process for making them. Said compound powder is a mixture composing of powder A and powder B, the content of powder A is 50-96 wt % and the content of powder B is 4-50 wt %, wherein powder A is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder; powder B bears different requirement characteristics from powder A and is at least one selected from iron powder, Fe—Si powder, Fe—Si—Al powder, Fe-based nanocrystalline powder, Fe-based amorphous powder, Fe—Ni powder and Fe—Ni—Mo powder. Said powder B adopts Fe-based amorphous soft magnetic powder with good insulation property as insulating agent and thus core loss of magnetic powder core decreases. The decrease of magnetic permeability of magnetic powder core resulting from a traditional insulating agent is remedied and the initial magnetic permeability of magnetic powder core is improved by taking advantage of soft magnetic properties of Fe-based amorphous powder.

    摘要： Evaluating a validation vector includes receiving a network having nodes and a target set that includes one or more nodes of the network. The following steps are repeated until the nodes of the target set have been selected. A node is selected from the target set, and a tag is assigned to the node, where the tag represents an error of a value of a variable corresponding to the node. A test environment specifying a propagation path from an input, through the node, and to an output is generated. The test environment is translated into a validation vector, and the tag is propagated to the output according to the validation vector. After repeating the steps, coverage for the validation vectors is determined in accordance with the propagation to evaluate the one or more validation vectors.

    摘要： A plasma processing apparatus includes a chamber (20) and a target (25) above the chamber (20). The surface of the target (25) contacts the processing area of the chamber (20). The chamber (20) includes an insulating sub-chamber (21) and a first conductive sub-chamber (22), which are superposed. The first conductive sub-chamber (22) is provided under the insulating sub-chamber (21). The insulating sub-chamber (21) is made of insulating material, and the first conductive sub-chamber (22) is made of metal material. A Faraday shield component (10) which is made of metal material or insulating material electroplated with conductive coatings and includes at least one slit is provided in the insulating sub-chamber (21). An inductance coil (13) surrounds the exterior of the insulating sub-chamber (21). The problem about the wafer contamination due to particles formed on the surface of the coil during the sputtering process can be solved by using the plasma processing apparatus.
