Code generation by using integer-controlled dataflow graph

Integer-Controlled Dataflow (IDF) and its code generation applications in Ptolemy are presented. In IDF graphs, which specify data processing systems, data token flow is controlled by integer control tokens and states of actors at run-time. The firing order of actors (schedule) is determined at compile-time, however, the actors are conditionally activated at run-time. This static schedule contributes to effective simulation of systems. IDF supports code generation. This enables code generation from program graphs that include conditional jumps, loops and repetitions, and greatly improves the practical usability of the program synthesis in Ptolemy
