Abstract
A digital signal processor receives samples of a first digital signal which is to be decimated and samples of a second digital signal which is to be interpolated. A digital signal processing engine performs a decimation function on samples of the first digital signal and an interpolation function on samples of the second digital signal on a time-shared basis. The digital signal processor has a first dual memory space for storing the samples of the first digital signal and a second dual memory space for storing the samples of the second digital signal. Outputs retrieved from a dual memory space are pre-added and applied to a multiplication and accumulation stage which operates on the pre-added outputs and a filter coefficient of a digital filter.
