摘要： Circuits, methods, and apparatus that isolate an input register from spurious transitions on a DQS signal. One example receives an enable signal from a core. A logic circuit, which may be referred to as a one-half period circuit, shortens enable pulses at their front end by one-half a period. The shortened enable signal is passed to a storage element such as a register. Active pulses of the shortened enable signal clear the register, which provides a control signal closing a switch, such as an AND gate. The switch passes the DQS signal to the input register when closed and isolates the input register from the DQS signal when open. The shortened enable signal prevents the switch from opening early and passing spurious transitions on the DQS signal, for example during back-to-back non-consecutive read cycles.

摘要： A method is provided for repairing a surface portion of an article including a metallic environmental resistant coating on a substrate. The coating includes a coating outer portion bonded with the substrate through a diffusion zone that includes at least one feature, for example Al and/or an intermetallic phase, in an amount detrimental to application of a metallic replacement coating and/or repair of the article. The method comprises removing the coating outer portion to expose a surface of the diffusion zone. The substrate and the diffusion zone are heated at a temperature and for a time sufficient to diffuse and/or dissolve at least a portion of the at least one feature in the exposed surface and in a portion of the diffusion zone beneath the exposed surface to a level below the detrimental amount. This provides a replacement surface portion integral with diffusion zone. Then a metallic replacement coating outer portion is applied to the replacement surface portion. Provided is a coated article comprising a substrate and a metallic environmental resistant coating bonded with the substrate. The coating comprises an inner modified portion of the substrate integral with the substrate, an outer diffusion zone integral with the inner portion, and a metallic environmental resistant coating outer portion integral with the outer diffusion zone. In some forms, the coated article includes a thermal barrier coating over the metallic coating outer portion.

摘要： A turbine nozzle segment includes a single hollow airfoil extending radially between radially outer and inner band segments. The airfoil has an airfoil wall with pressure and suction sides extending axially between leading and trailing edges of the airfoil. The airfoil wall surrounds a bifurcated cavity and a bifurcating rib extends through the bifurcated cavity and between the pressure and suction sides of the airfoil wall dividing the bifurcated cavity into forward and aft cavities. A stiffening rib extends radially outwardly from and along a radially outer surface of the outer band segment and axially and circumferentially from a pressure side forward corner of the outer band segment to the bifurcating rib. The outer and inner band segments, the bifurcating rib, and the stiffening rib are integral and made from a unitary one-piece casting.

摘要： Read interface circuitry is disclosed that facilitates using a source-synchronous clock signal to calibrate the read interface. In one embodiment, configurable read interface circuitry allows a particular read path to be configured for use in calibrating a read interface of the destination device. In particular, a plurality of read paths are provided, each read path having a configurable multiplexor (“mux”) coupled to a capture register of the read path such that the mux can be configured to select either an input coupled to an inverted output of the capture register or an input coupled to a prior register in the read data path. When the inverted output of the capture register is selected, a source-synchronous clock signal (e.g., DQS or delayed DQS signal) provided at the capture register's clock input results in a toggle signal at the capture register's output. In one embodiment, that toggle signal is provided to a re-sync register clocked by a re-sync clock signal. This toggle signal, together with another toggle signal generated at a toggle register coupled to the re-sync clock signal, are compared for various possible phases of the re-sync clock signal to determine a preferred phase of the re-sync clock signal. For other read paths, a mux coupled to a similar capture register is configured to select an input coupled to a prior register in the read path so that the read path can act as a path for incoming data signals (e.g., DQ signals).

摘要： Circuits, methods, and apparatus for transferring data from a device's input clock domain to a core clock domain. One example achieves this by using a retiming element between input and core circuits. The retiming element is calibrated by incrementally sweeping a delay and receiving data at each increment. Minimum and maximum delays where data is received without errors are averaged. This average can then be used to adjust the timing of a circuit element inserted in an input path between an input register clocked by an input strobe signal and an output register clocked by a core clock signal. In one example, an input signal may be delayed by an amount corresponding to the delay setting. In other examples, each input signal is registered using an intermediate register between the input register and the output register, where a clock signal is delayed by an amount corresponding to the delay setting.

摘要： Circuits, methods, and apparatus for the dynamic control of calibration data that adjusts the timing of input and output signals on an integrated circuit. This dynamic control allows input and output circuits to self-calibrate by compensating for temperature and voltage changes in an efficient manner, without the need for device reconfiguration. Calibration settings can be maintained while new calibration settings are loaded. Skew between clock and data signals, as well as among multiple data signals, can be reduced. Dynamic control is achieved while consuming only a minimal resources including route paths.
