Abstract

The paper models the Specification and Description Language (SDL) for systems that rely on one buffer for both process communication and task scheduling. The need for this arose because Ericsson Telecommunications Ltd. has developed a system that is built on this architecture and wants to use SDL as an implementation language. The scope has been limited to defining the semantics of SDL that relate to processing order because of the characteristics of a single communication buffer. The conclusion is that with the semantics in place, it will be possible to reason as to the properties of a system and it may also be possible to create a software tool directly from the semantic definitions for automatic reasoning
