A Petri net based method for resource estimation: an approach considering data-dependency, causal and temporal precedences

This work presents a combined reachability-structural methodology for computing the number of functional units in hardware/software co-design context considering timing constraints. The proposed method extends some previous works in the sense that data-dependency has been captured and considered in the functional unit estimation methodology. The proposed hardware/software co-design framework uses the Petri net as common formalism for performing quantitative and qualitative analysis
