A framework for implementing reusable digital signal processing modules

Abstract

A framework for implementing reusable digital signal processing modules is presented. Based on a cellular structure, it offers a high level of configurability. With its predefined control strategy, and its generic architecture, the framework allows a fast and efficient implementation of digital signal processing applications. As a practical example, the implementation of a frequency estimator, called the Crozier algorithm, is presented. Advantages observed when implementing the algorithm with the proposed framework are demonstrated.
