Announcements

• A Ptolemy User's Manual is available for check out in the Learning Resource Center (ENS 507).

Lecture

• Dataflow is a domain-specific specification language. It models streaming signal processing well. It is not well suited for general-purpose computing. Consider a word processor that uses a large amount of memory to represent the state of the program. Word processing commands work alter the state. This functionality is not represented well in pure dataflow modeling.

• Lecture on Synchronous Dataflow is available as slides 1-8 and 28-39 of the lecture Dataflow Languages in PowerPoint and PDF formats
  • Notes on Synchronous Dataflow, Part 1
  • Notes on Synchronous Dataflow, Part 2
  • Dataflow architecture is not a good match for a general-purpose desktop processor.
