Abstract:
The rising complexity in systems design, and the shift in the hardware/software functionality boundary has spurred research into development of EDA (Electronic Design Automation) tools at the systems level. Codesign is a methodology that proposes an integrated approach to systems design unifying both hardware and software approaches. Cosynthesis is a major field of research within codesign; cosynthesis takes a behavioural description and generates a hardware/software partition which satisfies system constraints. Current research is concerned with the automatic partitioning of systems. COSYN was developed to address the cosynthesis of embedded systems. A CIPN (Coloured Interpreted Petri Net) is used to model multiple processes and interprocess communication. The partitioning algorithm, which adopts a fine-grained approach to system partitioning (it considers moving nodes at the basic block level), is based on selecting blocks based on their potential speedup and extra hardware requirements, using hardware and software execution time estimators. The interdependence between interprocess communication primitives is exploited to achieve a better hardware/software partition. Results for an input example pdi are given which illustrate the benefits of the approach presented in this thesis.
