Abstract: Due to design constraints, many digital systems are implemented as mixed hardware and software components. An informal choice of where implementing a part of the system - either in software or in hardware - can produce incorrect or unsatisfactory results. Codesign methodologies have been developed to aid the development of such systems. The partitioning phase is one of the tasks carried out by a codesign methodology. It divides the original system into components taking into account software or hardware implementation. This work presents a model to carry out data dependency analysis, which is one of the aspects considered for the partitioning algorithm of the PISH codesign methodology. Quantitative analysis is performed using a Petri net model derived from occam specification of the system.
Keywords: PISH, Petri nets, codesign methodologies, data dependency analysis, hardware/software codesign.
