A Lightweight Dataflow Approach for Design and Implementation of SDR Systems

Model-based design methods based on dataflow modelsof computation are attractive for design and implementation
of wireless communication systems because
of their intuitive correspondence to communication system
block diagrams, and the formal structure that is
exposed through formal dataflow representations (e.g.,
see [2]).
In this paper, we introduce a novel lightweight
dataflow (LWDF) programming model for model-based
design and implementation of wireless communication
and software-defined radio systems. The approach is
suitable for improving the productivity of the design
process; the agility with which designs can be retargeted
across different platforms; and the quality of derived
implementations. By “lightweight”, we meant that the
programming model is designed to be minimally intrusive
on existing design processes, and require minimal
dependence on specialized tools or libraries. This allows
designers to integrate and experiment with dataflow
modeling approaches relatively quickly and flexibly into
existing design methodologies and processes.
