There has been a proliferation of block-diagram environments for specifying and prototyping
DSP systems. These include tools from academia like Ptolemy [6], and commercial tools like
SPW from Cadence Design Systems, and Cossap from Synopsys. The block diagram
languages used in these environments are usually based on dataflow semantics because
various subsets of dataflow have proven to be good matches for expressing and modeling
signal processing systems. In particular, synchronous dataflow (SDF)[14] has been found to …
