Today many applications in the vehicle are demanding more processing power. Any change in architecture to accommodate continuous change in requirements is becoming more and more tedious. Therefore, the concept of fixed or hardcoded architecture approach will be finding limited applications in the future. Most of the system developers are moving towards a model driven approach to create the architecture from concept. Processor architecture models created must be configurable and accurately execute the newly configured instructions set. The architecture created could meet the processing demand of vehicle applications like powertrain, Infotainment, for example, in terms of, processing power, connectivity and standard interfaces. These architectural models could serve as good innovative platform for performance analysis, system characterization and failure mode analysis.
