  • Patent number: 9788011
    Abstract: This invention is a digital signal processor form plural sums of absolute values (SAD) in a single operation. An operational unit performing a sum of absolute value operation comprising two sets of a plurality of rows, each row producing a SAD output. Plural absolute value difference units receive corresponding packed candidate pixel data and packed reference pixel data. A row summer sums the output of the absolute value difference units in the row. The candidate pixels are offset relative to the reference pixels by one pixel for each succeeding row in a set of rows. The two sets of rows operate on opposite halves of the candidate pixels packed within an instruction specified operand. The SAD operations can be performed on differing data widths employing carry chain control in the absolute difference unit and the row summers.

  • Patent number: 9489197
    Abstract: This invention is a digital signal processor capable of performing correlation of data with pseudo noise for code division multiple access (CDMA) decoding using clusters. Each cluster includes plural multipliers. The multipliers multiply real and imaginary parts of packed data by corresponding pseudo noise data. Within a cluster the real parts and the imaginary parts of the products are summed separately. This forms plural complex number outputs equal in number to the number of clusters. The pseudo noise data is offset relative to the data input differing amounts for different clusters. The clusters are divided into first half clusters receiving data from even numbered slots and second half clusters receiving data from odd numbered slots. The correlation unit includes a mask input to selectively zero a multiplier product.

  • Patent number: 9448767
    Abstract: A predictive adder produces the result of incrementing and/or decrementing a sum of A and B by a one-bit constant of the form of the form 2k, where k is a bit position at which the sum is to be incremented or decremented. The predictive adder predicts the ripple portion of bits in the potential sum of the first operand A and the second operand B that would be toggled by incrementing or decrementing the sum A+B by the one-bit constant to generate and indication of the ripple portion of bits in the potential sum. The predictive adder uses the indication of the ripple portion of bits in the potential sum and the carry output generated by evaluating A+B to produce the results of at least one of A+B+2k and A+B?2k.
