A framework for embedded system specification under different models of computation in SystemC

This paper presents a heterogeneous specification methodology built on top of the standard SystemC kernel. The methodology enables abstract specification supporting heterogeneity, which in this context entails the ability to describe and connect parts of the system specification under different models of computation (MoCs). A main and distinguishing contribution of the methodology is that the support is provided while maintaining the standard kernel of SystemC unchanged, by means of a set of specification rules and a heterogeneous support library built on top of the SystemC standard library. This is possible thanks to an abstraction technique that can integrate any new MoC that can be abstracted over the underlying discrete-event simulation kernel. Primitives, guidelines and rules of the specification methodology, including those related to heterogeneous support, and the basis of the abstraction technique are described. Experimental results demonstrate the benefits of the methodology
