Synthesis and Optimization of Pipelines for HW Implementations of Dataflow Programs

Marco Mattavelli, Anatoly Prihozhy, Ab Al Hadi Bin Ab Rahman, Endri Bezati

This paper introduces a new methodology for pipeline synthesis with applications to data flow high-level system design. The pipeline synthesis is applied to dataflow programs whose operators are translated into graphs and dependencies relations that are th ...
