  • Multiple processor interface, synchronization, and arbitration scheme using time multiplexed shared memory for real time systems
    Patent number: 6473821
    Abstract: An arbitration and synchronization method and system for allowing multiple processors to access a shared memory includes an arbitrator. The arbitrator is operable with the processors for enabling each of the processors exclusive access to the memory for a predetermined time period on a rotating basis. In operation, a time period of a time frame is associated with each of the processors. The time periods of the time frame are then counted. The arbitrator then enables a processor to have exclusive access to the shared memory for the time period associated with the processor when the counted time period is the time period associated with the processor.

  • Dither noise source with notched frequency spectrum
    Patent number: 6173003
    Abstract: A dither signal source generates a dither signal which is spectrally shaped in a desired manner. One or more notches are located at desired frequencies while minimizing the hardware required in a digital signal processor for generating the digital random noise for the dither signal source. The notched dither signal can be added to an analog signal prior to digitization to reduce quantization distortion without adding noise to the frequency range of interest.
