  • Patent number: 8576924
    Abstract: A video processing apparatus and methodology are implemented as a combination of a processor and a video decoding hardware block to decode video data by performing piecewise processing of overlap smoothing and in-loop deblocking in a macroblock-based fashion. With this approach, a smaller on-board memory may be used for the in-loop filtering operations of the video decoding hardware block. By pipelining the piecewise processing operations, latency in the filtering operations is hidden and the filtering output is smoothed, thereby avoiding the need for bursts of fetching and storing of blocks.

  • Patent number: 8570067
    Abstract: An integrated circuit is capable of controlling a communication signal by using power ramp controlled communication buffer logic to generate an outgoing communication signal based on a detected voltage on a voltage source. The voltage source is necessary to supply power for power ramp controlled communication buffer logic. The voltage on the voltage source may be detected using power ramp sensor logic. The outgoing communication signal is based on a core logic output signal if the detected voltage is greater than or equal to a predetermined voltage level. If, the detected voltage is less than the predetermined voltage level, the outgoing communication signal is predetermined to be one of: a tristate outgoing communication signal, a logic one outgoing communication signal and a logic zero outgoing communication signal. Power ramp controlled communication buffer logic may also generate a core logic input signal based on an incoming communication signal in response to the detected voltage.

  • Patent number: 8570881
    Abstract: A technique for characterizing a communications interface includes determining a voltage margin and a timing margin of the interface based on data sampled by a sampling device of a receiver of the interface. In at least one embodiment of the invention, a method for determining margin associated with a receiver circuit of an integrated circuit includes periodically sampling a signal over a time period by a receiver sampling circuit of the receiver circuit to generate a sampled version of the signal. The method includes incrementally varying a value of the parameter associated with the signal. The varying of the parameter is through a range of values of the parameter over the time period. The method includes determining a margin value of the receiver circuit associated with the parameter based, at least in part, on the sampled version of the signal.

  • Patent number: 8570783
    Abstract: Content-Addressable Memory (CAM) arrays and related circuitry for integrated circuits and CAM array comparison methods are provided such that relatively low power is used in the operation of the CAM circuitry. A binary value pair is stored in a pair of CAM memory elements. A comparison signal is provided to comparator circuitry that uniquely represents the stored binary values. A match signal is input to the comparator circuitry that uniquely represents a binary value pair to be compared with the stored binary value pair. In one example, a transistor is operated to output a positive match result signal only on a condition that the comparison signal provided to the comparator circuitry and match signal input to the comparator circuitry represent the same binary value pair. In that example, no transistor of the comparator circuitry is operated when the comparison signal provided to the comparator circuitry and match signal input to the comparator circuitry represent different binary value pairs.

  • Patent number: 8570113
    Abstract: A method and circuitry for calibrating the gain of a VCO (voltage controlled oscillator) is disclosed. In one embodiment, a circuit includes a comparator configured to provide a first indication if the VCO gain is not within the specified gain range, and a second indication if the VCO is within the specified gain range. The circuit further includes a control unit configured to, upon occurrence of at least a first cycle of a clock signal, cause adjustment of the VCO gain responsive to receiving the first indication. For each one or more successive cycles of the clock signal, the control unit is configured to cause corresponding adjustments of the VCO gain until the comparator provides the second indication. The control unit is configured to discontinue adjustments to the VCO gain responsive to receiving the second indication.

  • Patent number: 8570090
    Abstract: Electronic component protection power supply clamp circuits comprising a plurality of p-type channel metal-oxide-semiconductor (PMOS) and n-type channel metal-oxide-semiconductor (NMOS) transistors are described. These clamp circuits use a feedback latching circuit to retain an electrostatic discharge (ESD)-triggered state and efficiently conduct ESD current that has been diverted into the power supply, in order to dissipate ESD energy. The feedback latching circuit also maintains a clamp transistor in its off state if the clamp circuit powers up untriggered, thus enhancing the clamp circuit's immunity to noise during normal operation. Passive resistance initialization of key nodes to an untriggered state, as well as passive resistance gate input loading of a large ESD clamping transistor, further enhances the clamp circuit's immunity to false triggering.

  • Patent number: 8564030
    Abstract: A semiconductor device fabrication process includes forming insulating mandrels over one or more replacement metal gates on a semiconductor substrate. The mandrels include a first insulating material. Each mandrel has approximately the same width as its underlying gate with each mandrel being at least as wide as its underlying gate. Mandrel spacers are formed around each insulating mandrel. The mandrel spacers include the first insulating material. Each mandrel spacer has a profile that slopes from being wider at the bottom to narrower at the top. A second insulating layer of the second insulating material is formed over the transistor. Trenches to the sources and drains of the gates are formed by removing the second insulating material from portions of the transistor between the mandrels. Trench contacts to the sources and drains of the gates are formed by depositing conductive material in the first trenches.
