Abstract :
The paper presents an overview of transformations for DSP programs given in form of coarse-grain data-flow graphs. The goal is to produce a functionally equivalent data-flow graph with improved characteristics, regarding modeling and/or implementation of DSP software. Retiming, unfolding, vectorization, clustering as well as node/arc set extensions are discussed. As an example, an application of the presented transformations to the design of a satellite receiver is presented.
