  • Patent number: 9092227
    Abstract: A vector slot processor that is capable of supporting multiple signal processing operations for multiple demodulation standards is provided. The vector slot processor includes a plurality of micro execution slot (MES) that performs the multiple signal processing operations on the high speed streaming inputs. Each of the MES includes one or more n-way signal registers that receive the high speed streaming inputs, one or more n-way coefficient registers that store filter coefficients for the multiple signal processing, and one or more n-way Multiply and Accumulate (MAC) units that receive the high speed streaming inputs from the one or more n-way signal registers and filter coefficients from one or more n-way coefficient registers. The one or more n-way MAC units perform a vertical MAC operation and a horizontal multiply and add operation on the high speed streaming inputs.

  • Patent number: 8654873
    Abstract: In one embodiment, a Television (TV) receiver to perform a method of synchronizing a demodulator at a Viterbi decode input in the TV receiver using one or more bit de-interleaved even and odd Orthogonal Frequency Division Multiplexing (OFDM) symbols is provided. The method includes (i) performing a Viterbi decoding on the bit de-interleaved even and odd OFDM symbols when a frame boundary does not exist for the bit de-interleaved even and odd OFDM symbols, (ii) performing a convolutional encoding on an decoded data output of the Viterbi decoding, (iii) determining whether an output of the convolutional encoding of the bit de-interleaved OFDM symbols matches an input at a Viterbi decode, and (iv) determining whether the output of the convolutional encoding of the bit de-interleaved even and odd OFDM symbols matches with a SYNC pattern or a SYNC? pattern to obtain a RS packet align boundary.
