Design of telecommunication electronic systems using a hardware/software co-design methodology

Design of real-time electronic systems is critical since these systems incl ude performance constraints as part of their requirements. The goal is to m ap all functions of such systems on to distributed hardware/software archit ecture in such a way that all performance constraints can be met. Hardware/ software co-design approaches are an important issue. The aim of this paper is to discuss a case study of an X25 system design using a hardware/softwa re co-design methodology. Several alternatives are discussed with respect t o their performance. A prototype of the X25 system, which correctly impleme nts the system functionality while meeting real-time requirements, has been experimentally checked.
