Optimized software synthesis for synchronous dataflow

This paper reviews a set of techniques for compiling dataflow-based, graphical programs for digital signal processing (DSP) applications into efficient implementations on programmable digital signal processors. This is a critical problem because programmable digital signal processors have very limited amounts of on-chip memory and the speed power, and financial cost penalties for using off-chip memory are often prohibitively high for the types of applications, typically embedded systems, in which these processors are used. The compilation techniques described in this paper are developed for the synchronous dataflow model of computation, a model that has found widespread use for specifying and prototyping DSP systems
