This chapter first introduces two types of graphical representations of digital signal processing algorithms including signal flow graph (SFG) and data flow graph (DFG). Since SFG and DFG are in general used for analyzing structural properties and exploring architectural alternatives using high-level transformations, such transformations including retiming, pipelining, unfolding and folding will then be addressed. Finally, their real-world applications to both hardware and software design will be presented.
