Abstract: A re-sampler comprises a first CSD multiplier configured to receive input samples, a first accumulator coupled to the first CSD multiplier and configured to form a first MAC unit with the first CSD multiplier, a second CSD multiplier configured to receive the input samples, and a second accumulator coupled to the second CSD multiplier and configured to form a second MAC unit with the second CSD multiplier, wherein the re-sampler is configured to generate output samples based on the input samples. A method comprises receiving, by a first CSD multiplier, input samples, receiving, by a second CSD multiplier, the input samples, generating coefficients, scaling, using the first CSD multiplier and the second CSD multiplier, the input samples with coefficient vectors associated with the coefficients to form coefficient vector scaled input samples, and generating output samples based on the coefficient vector scaled input samples. The CSD multipliers may be MC-CSD multipliers.
