  3. "Finally, there are rare cases in which the structured primitives in StreamIt have been inadequate

for representing a streaming communication pattern. Figure 2-20 illustrates an example from video compression, where each parallel filter performs a motion prediction for a fixed area of the screen. Between successive frames, each filters shares its prediction with its neighbors on either side. While this could be represented with a feedback loop around the entire computation, there would be complicated interleaving involved.
