  • Patent number: 9753732
    Abstract: In accordance with some embodiments of the present invention, a branch prediction unit for an embedded controller may be placed in association with the instruction fetch unit instead of the decode stage. In addition, the branch prediction unit may include no branch predictor. Also, the return address stack may be associated with the instruction decode stage and is structurally separate from the branch prediction unit. In some cases, this arrangement reduces the area of the branch prediction unit, as well as power consumption.

  • Publication number: 20170138762
    Abstract: This invention discloses a door-window sensor which can be integrated with the associated fittings of the door and window. The sensor cannot be seen from appearance of the door and window, thus making the door and window beautiful and elegant on the whole. It can be installed easily without the limitation of door and window in the external dimension; it is used to determine whether the door and window is locked or closed; its cost is at a lower level. For the sensor, the door and window consists of frame and leaf. The leaf is driven by the motor to rotate around the connected axis and locked to the frame by means of lock. It gets close to inner side of the frame when closed and away from inner side of the frame when opened. The sensor consists of induction generating components, inductive device and data processing unit.

  • Patent number: 9576673
    Abstract: Disclosed herein are techniques for sensing multiple reference levels in non-volatile storage elements without changing the voltage on the selected word line. One aspect includes determining a first condition of a selected non-volatile storage element with respect to a first reference level based on whether a sensing transistor conducts in response to a sense voltage on a sense node. Then, a voltage on the source terminal of the sensing transistor is modified after determining the first condition with respect to the first reference level. A second condition of the selected non-volatile storage element is then determined with respect to a second reference level based on whether the sensing transistor conducts in response to the sense voltage on the sense node. This allows two different reference levels to be efficiently sensed. Dynamic power is saved due low capacitance of the sensing transistor relative to the sense node.

  • Publication number: 20160345190
    Abstract: The present disclosure provides QoS management methods, QoS management devices and a QoS management system. According to the present disclosure, with respect to a terminal in a dual-connectivity scenario, QoS parameter thresholds corresponding to a QoS parameter may be re-allocated to an MeNB and an SeNB for the terminal in accordance with an initial value corresponding to the QoS parameter of the terminal, so as to ensure that a QoS parameter value finally acquired by the terminal and corresponding to the QoS parameter does not exceed a numerical range defined by the initial value of the QoS parameter. As a result, it is able to match services provided to the terminal with the QoS that should have been possessed thereby in the case that the terminal is served by the MeNB and the SeNB, thereby to control the QoS of the terminal.

  • Publication number: 20160254048
    Abstract: Methods for precharging bit lines using closed-loop feedback are described. In one embodiment, a sense amplifier may include a bit line precharge circuit for setting a bit line to a read voltage prior to sensing a memory cell connected to the bit line. The bit line precharge circuit may include a first transistor in a source-follower configuration with a first gate and a first source node electrically coupled to the bit line. By applying local feedback from the first source node to the first gate, the bit line settling time may be reduced. In some cases, a first voltage applied to the first gate may be determined based on a first current drawn from the first bit line. Thus, the first voltage applied to the first gate may vary over time depending on the conductivity of a selected memory cell connected to the bit line.
