  • Patent number: 6975692
    Abstract: In a method of demodulating and decoding an encoded interleaved signal, a received encoded interleaved signal is demodulated, thereby producing soft-decision demodulated output words. Thereafter, the soft-decision demodulated output words are de-interleaved and scaled, thereby producing de-interleaved and scaled words. The scaling is performed for a plurality of successively demodulated output words at a time, thereby applying a scale factor that is substantially constant over the entire span of an interleaving frame. The de-interleaved and scaled words are word-length-reduced words. Finally, the de-interleaved and scaled words are decoded.

  • Patent number: 6970895
    Abstract: A delay addressed data path register file is designed for use in a programmable processor making up a cell in a multi-processor or array signal processing system. The delay addressable register file is particularly useful in, inter alia, adaptive filters where the filter update latency is variable, interpolation filters where the interpolation factor needs to be programmable, and decimation filters where the decimation factor needs to be programmable. The programmability is achieved in an efficient manner, reducing the number of cycles required to perform this task. A single parameter, the “delay limit” value, is programmed at start-up, setting up an internal delay-line within the register file of the processor. Thus, any of the delayed registers can be addressed by specifying the delay index during run-time. The delay line advances one location, modulo “delay-limit”, when the processing loop starts a new iteration.

  • Patent number: 6963987
    Abstract: In a reduced power mode a first data processing unit forming part of a data processing system offers a second data processing unit access to its associated memory in order to optimize the use of energy and available resources. The first data processing unit requires reduced storage space in the reduced power mode, which remaining storage space can be made available to the second data processing unit. The memory associated to the second data processing unit can be switched off to save energy, or can be removed altogether if the second data processing unit only operates in the reduced power mode.

  • Patent number: 6959053
    Abstract: A method of searching for a predefined code in a bit stream, the method comprising initiating a first search for correlation of the bit stream with a reference code applied to the bit stream at a first plurality of different times according to a first resolution to produce a first set of correlation values and associated times. Then a second search is initiated for correlation of the bit stream with the reference code applied to the bit stream at a second plurality of different times to produce a second set of correlation values and associated times, the reference code being offset in time from a maximal correlation value of the first set such that the reference code is applied to the bit stream at times other than times of the first plurality. Then, out of the first and the second sets a maximal correlation value is selected for use in calculating a strength of the predefined code in the bit stream.

  • Patent number: 6954628
    Abstract: A radio receiver is configurable to operate in both low-IF and zero-IF modes with maximum re-use of of analogue and digital circuitry between modes. The receiver comprises a quadrature down-converter for generating in-phase (I) and quadrature (Q) signals at an intermediate frequency and a complex filter for performing image rejection filtering. In the low-IF mode, one of the outputs (Q) of the filter is terminated, the other (I) is digitised by a non-complex ADC then the digital signal is filtered and decimated. Quadrature-related IF signals are then re-generated before down-conversion and demodulation. In the zero-IF mode, both outputs of the filter are digitised and processed in parallel before demodulation. By enabling analogue-to-digital conversion and channel filtering to be performed at low-IF on non-complex signals, use of just two non-complex ADCs is possible, thereby avoiding duplication of circuitry and providing significant power savings.

  • Patent number: 6954727
    Abstract: A method of reducing sinusoidal artifact generation in a vocoder. In one embodiment, the present invention first receives a determined input energy threshold value. The input energy threshold value is the value below which it is believed that a suspected noise-inducing codebook excitation vector will be generated by the vocoder. Next, provided that an input signal is received having an energy value lower than the input energy threshold value, the present invention uses a codebook excitation vector selection process to prevent the suspected noise-inducing codebook excitation vector from being continuously generated. In one embodiment, the codebook excitation vector selection process is a randomization codebook excitation vector selection process. In so doing, the present embodiment prevents the creation of harmonics during zero or low-energy input periods.

  • Patent number: 6936890
    Abstract: A RESURF trench gate MOSFET has a sufficiently small pitch (close spacing of neighbouring trenches) that intermediate areas of the drain drift region are depleted in the blocking condition of the MOSFET. However, premature breakdown can still occur in this known device structure at the perimeter/edge of the active device area and/or adjacent the gate bondpad. To counter premature breakdown, the invention adopts two principles: the gate bondpad is either connected to an underlying stripe trench network surrounded by active cells, or is directly on top of the active cells, and a compatible 2D edge termination scheme is provided around the RESURF active device area. These principles can be implemented in various cellular layouts e.g.

  • Patent number: 6931056
    Abstract: A method of code phase tracking for CDMA type communication is disclosed together with apparatus including a GPS receiver (10 to 15) for the same. The method uses a modified early-minus-late correlation function to determine the code phase error between a target pseudorandom noise code of an incoming signal and locally generated replica codes. The early-minus-late correlation function is modified compared to the true function whereby the gradient of the modified function at zero code phase error is increased. This may be achieved my modifying the early-minus-late correlation function after its derivation.
