Title
Communicating Transaction Processes: An MSC-Based Model of Computation for Reactive Embedded Systems
Abstract
Message Sequence Charts (MSC) have been traditionally used to depict execution scenarios in the early stages of design cycle. MSCs portray inter-object interactions. Synthesizing intra-object executable specifications from an MSC-based description is a non-trivial task. Here we present a model of computation called Communicating Transaction Processes (CTP) based on MSCs from which an executable specification can be extracted in a straightforward manner. Our model describes a network of communicating processes in which the processes interact via common action labels. Each action is a non-atomic interaction described as a, guarded choice of MSCs. Thus our model achieves a separation of concerns: the high-level network of processes depicting intra-process computations and control flow, while the common non-atomic communication actions capture inter-process interaction via MSCs. We show how to extract an ordinary Petri net from a CTP model thereby leading to a standard operational semantics. We also discuss the connection of our formalism to Live Sequence Charts, an extension of MSCs which also has an executable semantics.
