A CoDesign experience with the MCSE methodology

We describe the experimentation of a codesign process to develop a communication system which needs to correctly mix hardware and software parts to satisfy required performance. The system design process is based on the MCSE methodology and we show its usefulness for CoDesign (concurrent design). CoDesign is shown as an enhancement of the implementation specification step of MCSE. System partitioning is the result of an interactive procedure based on performance and cost evaluations. The complete description of the implementation is obtained by transformations of the functional description: C or C++ for the software part, VHDL for the hardware part. The links between the hardware and software parts are also synthesized. Such a procedure and associated tools lead to efficiently obtain system prototypes in an incremental manner.<
