  • Patent number: 10140458
    Abstract: A processing system implementing techniques for parallelized authentication encoding is provided. In one embodiment, the processing system includes an accumulator, a register representing a pipeline stage and a processing core coupled to the accumulator and to the register. The processing core is to split an input message into a first input stream and a second input stream. For each input stream, the processing core is further to add, to the accumulator, a data block from the input stream. Contents of the accumulator multiplied by a squared nonce value are stored in the register and a result of applying a modulo reduction operation to the contents of the register is stored in the accumulator. Thereupon, an authentication tag for the input message is generated based on the result stored in the accumulator and the contents of the register.

  • Patent number: 7860474
    Abstract: A method of controlling noise in a pulse width modulation circuit includes varying a sample frequency and a range of information levels, wherein each sample within a data sample stream at the sample frequency represents a level within the range of information levels, to shift in frequency noise generated at the sample frequency during encoding of the data sample stream into pulse width modulated patterns.

  • Patent number: 7826578
    Abstract: A data processing system including an input data port for receiving input data samples asynchronous to a native clock signal and having an input sample rate, a first sample rate converter for converting the data samples from the input sample rate to a sample rate synchronous with a rate of the native clock signal, and a data converter for converting data samples output from the first sample rate converter to another format. An analog to digital converter converts an analog signal into output data samples with a sample rate synchronous with the rate of the native clock signal, and a second sample rate converter converts the sample rate of the output data samples from the sample rate synchronous with the rate of the native clock signal to an output sample rate such that output data samples are asynchronous to the native clock signal.

  • Publication number: 20090135922
    Abstract: In a wireless communications system using Orthogonal Frequency Division Multiplex technology, changing the nature of the signals being transmitted/received may be used to reduce power consumption. In one embodiment, reducing the number of carriers that are being employed may be used to decrease power consumption by permitting a reduced clock rate for driving some of the circuitry. Similarly, increasing the duration of the symbols used to encode the data may be used to reduce the clock rate. Other power savings may be found by using single-rail processing, allowing some of the signal processing circuitry to simply be shut down.

  • Publication number: 20080232270
    Abstract: Arrangements for a reduced power consumption network device are disclosed. In one embodiment, the device can join the network by communicating with a second network compatible device. After the network connection is made the device can place communication configuration or network status processing components in a low power mode until the device detects an indication of a status change in a communication from the second device. When the status change is detected the device can activate the status processing components that were placed in the low power mode and these processing components can process the status change information to change a communication configuration. Significant power saving can be achieved by placing such components into the sleep mode.

  • Patent number: 7342525
    Abstract: Digital to Analog Conversion and sample conversion blocks are combined in order to reduce hardware and/or computational complexity. A novel DSM design is used to perform sample rate conversion. The DSM may also be used to perform other digital filtering functions, thus providing a single hardware/software technique to perform both functions. The invention includes a method and apparatus for converting input data samples provided at a first sample rate to an analog output signal. Input data samples are converted by a Delta Sigma Modulator (DSM) in a Digital to Analog Converter (DAC) to output data samples, where internal states of the DSM are updated at a second sample rate unequal to the first sample rate. At least one internal state of the DSM s modified to account for the time difference in response to a new input sample arriving at a time different from an update of the internal states of the DSM.
