Dataflow Transformations in High-level DSP System Design
Sankalita Saha, Sebastian Puthenpurayil, Shuvra S. Bhattacharyya · 2006
Dataflow graph transformations are important in many contexts of SoC implementation, particularly in the domain of signal processing. Most previous work on dataflow graph transformations has focused on synchronous dataflow and closely-related representations (e.g., see Lee and Messershcmitt (1987), Parhi (1995) and Zivojnovic et al., (1994). However, because SDF is limited to expressing static dataflow behaviors, modern SoC applications are often not fully amenable to SDF. In this paper, we discuss methods of modeling and transformation for more flexible forms of dataflow that are better suited to high-level design of modern signal processing systems
