Abstract

This work presents two approaches for computing the number of functional units in the PISH hardware/software codesign systtem. The proposed methods use Petri net as common formalism for performing quantitative analysis. The use of Petri net permits to use a specification non-dependent partitioning method. Particularly, Petri net as an Intermediate format allows to analyze properties of the specification and formally compute peformance indices which are Hsed in the partitioning process. This paper is devoted to describe those approaches. but an overview of the general hardware/software codesign method is also presented.
