Performance analysis of multiprocessor DSPs

This article introduces a composable component model that can be used for performance analysis of complex digital signal processinging (DSP) systems consisting of several computation resources communicating via some shared media. We review different methods of analyzing the performance of such communication-centric systems, including simulation, trace-based simulation, and symbolic methods. Finally, a component model that can be used to formally state the relationship between the usage and the processing capabilities of different computation and communication resources is established. Using this component model, we can analytically derive performance measures of complete DSP systems. We then illustrate the applicability of this component model with an example.
