  • Patent number: 7847864
    Abstract: All digital RF modulator. An RF modulator, implemented using only digital techniques, obviates the need for an additional board, implemented using discrete analog components, to perform the necessary modulation to provide the RF output signal for use with a display device (television). Modern displays typically include functionality to support a number of input types beyond an RF input. However, older, legacy displays typically only support inputs that are RF in nature. A fully integrated solution that performs the RF modulation of the output signal that may be used in such legacy types systems is provided using digital techniques.

  • Patent number: 7577699
    Abstract: Methods and apparatus for reducing precision of an input signal, by comparing a portion of the input signal to a preselected threshold value, and determining a selectable bias responsive to the comparison. By combining a portion of the input signal with the selectable bias, a reduced precision signal, having minimized or eliminated rounding error, is generated. The selectable bias corresponds to a predetermined characteristic of one of bias, an error signal, the input datum, the reduced precision datum, and a combination thereof.

  • Patent number: 6377619
    Abstract: Multiported register files are employed to implement the input delays necessary for finite impulse response (FIR) filter operation. A multiported register file is a memory, typically small, with at least one read port and one write port. Data written into the multiported register file may be read out therefrom in any desired order. The multiported register tile may have additional output ports from which the data stored therein may be read out, also in any desired order, and independent from the order of any other output port. At least one output of each multiported register file is coupled to the input of the next stage of the FIR filter, if any. In addition, each multiported register file feeds data from one output to the multiply-add portion of its associated stage of the FIR filter.
