Tools for designing signal processing systems with their semantic foundation in dataflow modeling often use high-level graphical user interface (GUI) or text based languages that allow specifying applications as directed graphs. Such graphical representations serve as an initial reference point for further analysis and optimizations that lead to platform-specific implementations. For large-scale applications,...
Parameterized Synchronous Dataflow (PSDF) has been used previously for abstract scheduling and as a model for architecting embedded software and FPGA implementations. PSDF has been shown to be attractive for these purposes due to its support for flexible dynamic reconfiguration, and efficient quasi-static scheduling. To apply PSDF techniques more deeply into the design flow, support for comprehensive...
The latest communication technologies invariably consist of modules with dynamic behavior. There exists a number of design tools for communication system design with their foundation in dataflow modeling semantics. These tools must not only support the functional specification of dynamic communication modules and subsystems but also provide accurate estimation of resource requirements for efficient...
For a number of years, dataflow concepts have provided designers of digital signal processing systems with environments capable of expressing high-level software architectures as well as low-level, performance-oriented kernels. But analysis of system-level trade-offs has been inhibited by the diversity of models and the dynamic nature of modern dataflow applications. To facilitate design space exploration...
For a number of years, dataflow concepts have provided designers of digital signal processing systems with environments capable of expressing high-level software architectures as well as low-level, performance-oriented kernels. To apply these proven techniques to new complex, dynamic applications, we identify repetitive sequences of atomic, repeatable actions ("modes") inside dynamic actors...
Dataflow formalisms have provided designers of digital signal processing systems with optimizations and guarantees to arrive at quality prototypes quickly. As system complexity increases, designers are expressing more types of behavior in dataflow languages to retain these implementation benefits. While the semantic range of DSP-oriented dataflow models has expanded to cover quasi-static and dynamic...
