Abstract
A system for processing sample sequences, that may include an input, a sequence of coupled registers, including an accumulator register, and first circuitry that may be coupled to the accumulator register and to the input. The input may be configured to receive a first number of sample sequences having two or more samples. To process the first number of sample sequences, the first circuitry may be configured to generate a current effective sample corresponding to the sample for each sample in each sample sequence, write the current effective sample to the accumulator register, and shift the contents of each register into a successive register in the sequence of registers. After processing, each register of at least a subset of the sequence of registers may hold a respective final effective sample that may correspond to a different position in a processed sample sequence.
