  • Patent number: 9372799
    Abstract: To enable efficient tracking of transactions, an acknowledgement expected signal is used to give the cache coherent interconnect a hint for whether a transaction requires coherent ownership tracking. This signal informs the cache coherent interconnect to expect an ownership transfer acknowledgement signal from the initiating master upon read/write transfer completion. The cache coherent interconnect can therefore continue tracking the transaction at its point of coherency until it receives the acknowledgement from the initiating master only when necessary.

  • Patent number: 9368355
    Abstract: Oxide growth of a gate dielectric layer that occurs between processes used in the fabrication of a gate dielectric structure can be reduced. The reduction in oxide growth can be achieved by maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth of the gate dielectric layer between at least two sequential process steps used in the fabrication the gate dielectric structure. Maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth also improves the uniformity of nitrogen implanted in the gate dielectric.

  • Patent number: 9369267
    Abstract: The effect of timing inaccuracy is compensated for in a communication receiver that receives a transmission of bits temporally separated by a bit interval. The compensation employs an oversampling clock whose frequency defines a sampling interval that is smaller than the bit interval, which bit interval is nominally a predetermined integer multiple of the sampling interval. The oversampling clock samples the received transmission to produce an incoming sample stream. The incoming sample stream is decoded by a plurality of different decoding operations to produce, respectively, a plurality of decoded sample streams. It is determined whether the received transmission is decodable from any of the decoded sample streams.

  • Patent number: 9369051
    Abstract: An interleaved forward voltage converter having a first inverter stage has a first transformer having a first secondary winding coupled to a filter inductor. A second converter stage has a second transformer having a second secondary winding coupled to the filter inductor. A diode is coupled between the first and second secondary windings to automatically connect the first and second secondary windings in series when a duty cycle of the converter exceeds 50%. An interleaved forward voltage converter can connect the two primary windings in either parallel or a series configuration. The two secondary windings can be connected in either parallel or a series configuration. Having the two primary windings in parallel and the two secondary windings in series allows the converter to operate with a lower input voltage. Having the two primary windings in series and the two secondary windings in a parallel configuration allows the converter to operate with a higher input voltage.

  • Patent number: 9369116
    Abstract: Circuits and methods for detecting the presence of a leading-edge phase-cut dimmer. The dimmer detector comprises an edge detector, a pulse stretcher and a filter. The edge detector detects whether an input signal has a rapidly rising edge and generates an output signal pulse if a rapidly rising edge is detected. If the edge detector outputs a signal pulse, the pulse stretcher generates a stretched pulse having a duration that is longer than the signal pulse received from the edge detector. The filter produces a dimmer detect signal that indicates whether a leading-edge phase-cut dimmer is detected. If the pulse stretcher output signal comprises at least a predetermined number of stretched pulses within a predetermined amount of time, the dimmer signal signals the presence of a leading-edge phase-cut dimmer.

  • Patent number: 9369043
    Abstract: A DC-DC converter includes a first differential voltage sensor to detect a first inductor current by sensing a first differential voltage across a first power stage of the DC-DC converter. A second differential voltage sensor detects a second inductor current by sensing a second differential voltage across a second power stage of the DC-DC converter. An integrator stage combines the first differential voltage from the first power stage and the second differential voltage from the second power stage to generate a compensation signal to adjust current balancing for the DC-DC converter.

  • Publication number: 20160165230
    Abstract: Checksum computation for video coding is provided that breaks the dependency between the color components of a picture in the prior art. More specifically, rather than computing a single checksum for a picture as in the prior art, a separate checksum is computed for each color component. Computing a separate checksum for each color component enables parallel computation of the component checksums. Methods are provided for computing three separate checksums after a picture is decoded. Methods are also provided for computing three separate checksums on a largest coding unit basis, thus allowing the checksums for a picture to be computed as the picture is being decoded.

  • Publication number: 20160164532
    Abstract: Disclosed is a circuit, such as a clock conditioner, that provides an improved ability to exit from holdover operations, most notably during conditions where the clock signal inputs to a PLL of the clock conditioner are significantly out of phase. The circuit utilizes the PLL to generate output clocks based on a reference clock and a feedback clock. During holdover mode, the PLL is unlocked. When the reference clock becomes available and holdover mode can be exited, a holdover controller issues a reset signal that triggers a synchronization of the phases of the inputs to the PLL. The reset signal causes the feedback divider component that generates the feedback clock input to reset its phase and adjust its divide ratio for at least the first divide cycle after restart so that its next rising edge will be phase-aligned with the reference clock. Once the two inputs of the PLL phase detector are phase-aligned, the PLL is re-enabled and the PLL smoothly resumes normal operation.
