Abstract: A method includes retrieving a plurality of datasets from respective memory registers of a memory and storing the retrieved plurality of datasets in respective register portions of a first register. A dataset of data-processing coefficients are stored in a second register. First processing is applied using, as the first operand, a first sub-set of dataset elements stored in the first register, and using, as the second operand, the data-processing coefficients, obtaining a first result. Second processing is applied using, as the first operand, a second sub-set of dataset elements stored in the first register comprised in a second window having a size equal to the dataset size, and using, as the second operand, the replica of the dataset of data-processing coefficients, obtaining a second result. An output is generated based on the first and second results. The first and second processing may perform multiply accumulate (MAC) operations.
