  • Patent number: 7895506
    Abstract: Embodiments of an iterative decoder with early-exit condition detection and methods for decoding are generally described herein. Other embodiments may be described and claimed. In some embodiments, a first codeword is generated from decoded bits after one or more half-iterations of an iterative decoder, a second codeword from decoded bits after an additional half-iteration of the iterative decoder, and the first and second codewords are compared to determine whether the decoded bits are valid. In some embodiments, double or triple codeword matching is selected based on an estimated signal-to-noise ratio (SNR) and the modulation level.

  • Patent number: 6760830
    Abstract: In one embodiment, a modulo addressing unit for a processor is described that includes a plurality of adders to generate an uncorrected target module address and at least one corrected target module address in parallel. A comparator selects one of the target module addresses a function of a base address (b) for a circular buffer, a length (L) of the circular buffer, an index address (I) and a modifier value (M). In one embodiment the comparator selects a first corrected target module address when I+M<B, a second corrected target module address when I+M>=B+L and an uncorrected module address when B<=I+M<B+L.
