Scenario-aware dataflow: Modeling, analysis and implementation of dynamic applications

Embedded multimedia and wireless applications require a model-based design approach in order to satisfy stringent quality and cost constraints. The Model-of-Computation (MoC) should appropriately capture system dynamics, support analysis and synthesis, and allow low-overhead model-driven implementations. This combination poses a significant challenge. The Scenario-Aware DataFlow (SADF) MoC has been introduced to address this challenge. This paper surveys SADF, and compares dataflow MoCs in terms of their ability to capture system dynamics, their support for analysis and synthesis, and their implementation efficiency.
