    摘要: Techniques are provided which may be used to reduce power consumed by memory circuits. In one example, a programmable logic device (PLD) includes a plurality of static random access memory (SRAM) cells adapted to configure the PLD for an intended use. A pair of bitlines are connected to the SRAM cells. At least one of the SRAM cells is adapted to provide data signals to the bitlines in response to a wordline signal received by the one of the SRAM cells during a read operation. A sense amplifier is connected to the bitlines and adapted to detect a data value from the data signals in response to a trigger signal received by the sense amplifier during the read operation. Logic is adapted to delay the trigger signal relative to the wordline signal to permit the data signals to settle before the sense amplifier detects the data value.

    摘要: Techniques are provided which may be used to reduce power consumed by memory circuits. In one example, a memory circuit includes a static random access memory (SRAM) cell. A pair of bitlines are connected to the SRAM cell. A precharge circuit is connected to the bitlines. The precharge circuit is adapted to precharge the bitlines immediately prior to read and write operations performed on the SRAM cell and float relative to the bitlines at other times.

    摘要: Searching is assisted by recognizing a selection of text from a document as an indication that a user wishes to initiate a search based on the selected text. The user is provided with query suggestions based on the selected text and the query suggestions are ranked based on a context provided by the document. The user may select the text by using a mouse, drawing a circle around the text on a touch screen, or by other input techniques. The query suggestions may be based on query reformulation or query expansion techniques applied to the selected text. Context provided by the document is used by a language model and/or an artificial intelligence system to rank the query suggestions in predicted order of relevance based on the selected text and the context.

    摘要: An electromagnetic induction apparatus for power transfer may include a first portion and a second portion. The first portion has at least one loop of central coil is winded on the central magnetic core, and the second portion has at least one loop of toroidal core winded on the toroidal magnetic core. When the first portion is inserted into the second portion, the toroidal coil is located around an outside periphery of the central coil. Since the central coil and the toroidal coil are mutual inductance on the same magnetic core, the electromagnetic induction efficiency is improved, leading to enhancing more than 50% of the power transmitted rate.
