Based on the methodology for the development of communication systems, a framework for early performance evaluation and hardware/software codesign of such systems is presented. We describe how performance requirements can be formulated in a formal way during the analysis phase of a project and how these requirements are used by the synthesis tools for(More)
A new approach for the translation of SDL specifications to a mixed hardware/software system is presented. Based on the computational model of communicating extended finite state machines (EFSM) the control flow is separated from data flow of the SDL process. Hence for the first time it is possible to generate a mixed hardware/software implementation of an(More)
This paper presents a prototyping platform for high performance communication systems together with a design methodology. Based on a formal design entry and nonfunctional design goals such as execution time and overall system cost, a software/hardware partitioning is generated and its performance is estimated with formal models. Valid partitionings are then(More)
A known problem in the area of hardware/software codesign is the selection of the proper interface between the different parts of the design. This paper presents a technique which eases the selection by combining different synthesis techniques together with rapid prototyping. Application field of the technique is the design of communication systems where C(More)

The ITU-T Specification and Description Language SDL gains more and more importance in the specification and implementation of real-time systems that possess additional non-functional requirements. In the past SDL was mainly used to describe the structure and the functional behavior of reactive systems, without considering non-functional aspects such as(More)
