A graphical notation for describing data flow in digital filters
Steve Terepin · 2005
This paper illustrates a graphical notation that provides a clear representation of the data flow in digital filters. The notation accommodates situations in which state variables are accessed and updated sequentially, and in which several arithmetic and data transfer operations take place concurrently. It has been found useful for verifying the correctness of algorithms developed for a dedicated LSI signal processor that has a high degree of functional parallelism.
