Abstract: A method of video decoding is provided that includes receiving a data stream comprising a sequence of syntax elements that were compressed using context-adaptive binary arithmetic coding (CABAC), such that the encoding of each bin of a bin string representative of a syntax element was performed by arithmetic encoding. Two consecutive bins of a syntax element are decoded in parallel. Speculative computation and prefetching is used to reduce the critical path and thereby improve processing speed.

Abstract: An apparatus employing control words to present a synthesized output signal having an output frequency and a delay with respect to an input signal includes: (a) A multiplexer receiving the input signal and having an output and an address input. (b) An output unit generates the output signal in response to a drive signal from the multiplexer. (c) A first register coupled with the multiplexer output. (d) A second register coupled with the multiplexer and the first register. The first register responds to a multiplexer output signal to provide a first control signal to the second register based upon the control words. The second register responds to the multiplexer output signal to provide a second control signal to the address input based upon the first control signal and the control words. The multiplexer presents the drive signal in response to the second control signal.

Abstract: Exemplary embodiments provide methods for implementing an ultra-high temperature (UHT) anneal on silicon germanium (SiGe) semiconductor materials by co-implanting carbon into the SiGe material prior to the UHT anneal. Specifically, the carbon implantation can be employed to increase the melting point of the SiGe material such that an ultra high temperature can be used for the subsequent anneal process. Wafer warpage can then be reduced during the UHT anneal process and potential lithographic mis-alignment for subsequent processes can be reduced. Exemplary embodiments further provide an inline control method, wherein the wafer warpage can be measured to determine the litho-mis-alignment and thus to control the fabrication process. In various embodiments, the disclosed methods can be employed for the fabrication of source/drain extension regions and/or source/drain regions of transistor devices, and/or for the fabrication of base regions of bipolar transistors.

Abstract: A system and method for power conversion synchronizes multiple phases at a desired phase angle difference. The power conversion involves variable frequency switching, fixed on-time and provides power factor correction. A relative measure of a phase angle difference between two phases permits each phase to be controlled to obtain the desired phase angle difference. The power conversion involves transition mode switching to help reduce switching losses. A phase angle difference detector may be provided for each phase. The various phases may have different inherent frequencies that vary with switching frequency, and are synchronized to an average frequency.

Abstract: A novel and useful fast hopping frequency synthesizer and transmitter associated therewith. The frequency synthesizer and transmitter incorporates a digitally controlled oscillator (DCO) adapted to operate open loop. Instantaneous frequency switching is achieved by changing an oscillator tuning word (OTW) to imitate the three oscillators of a UWB transmitter. In one embodiment, the DCO can change the frequency instantaneously within the 1/fT of the varactor devices used to construct the DCO. An all digital phase lock loop (ADPLL) is used for offline calibration prior to the start of packet transmission or reception. Any phase shift during the switching is tracked by a digital circuit in the transmitter. In a second embodiment, additional frequency accuracy is provided by use of a numerically controlled oscillator (NCO) that functions to generate a fine resolution complex exponential waveform which effectively shifts the synthesized frequency.

Abstract: A semiconductor device (1700), which comprises a workpiece (1201) with an outline (1711) and a plurality of contact pads (1205) and further an external part (1701) with a plurality of terminal pads (1702). This part is spaced from the workpiece, and the terminal pads are aligned with the workpiece contact pads, respectively. A reflow element (1203) interconnects each of the contact pads with its respective terminal pad. Thermoplastic material (1204) fills the space between the workpiece and the part; this material adheres to the workpiece, the part and the reflow elements. Further, the material has an outline (1711) substantially in line with the outline of the workpiece, and fills the space (1707) substantially without voids. Due to the thermoplastic character of the filling material, the finished device can be reworked, when the temperature range for reflowing the reflow elements is reached.

Abstract: Scan distributor, collector, and controller circuitry connect to the functional inputs and outputs of core circuitry on integrated circuits to provide testing through those functional inputs and outputs. Multiplexer and demultiplexer circuits select between the scan circuitry and the functional inputs and outputs. The core circuitry can also be provided with built-in scan distributor, collector, and controller circuitry to avoid having to add it external of the core circuitry. With appropriately placed built-in scan distributor and collector circuits, connecting together the functional inputs and outputs of the core circuitry also connects together the scan distributor and collector circuitry in each core. This can provide a hierarchy of scan circuitry and reduce the need for separate test interconnects and multiplexers.
