Abstract: A re-sampler comprises: a plurality of multipliers configured to receive an input sample; and a plurality of accumulators coupled to the multipliers and configured to form multiplier-accumulator (MAC) units with the multipliers, wherein the MAC units are configured to: compute partial products from the input sample, accumulate the partial products over clock cycles, and sequentially generate output samples based on the computing and the accumulating. A method comprises: receiving input samples; computing partial products from the input samples; accumulating the partial products over clock cycles; and sequentially generating output samples based on the computing and the accumulating.

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.
