Abstract
Real time embedded system design needs a contribution between architectures model, platforms and application specification in order to prototype a real time system from high level specification. In many case, one allocated solution prototype is not so good to answer the environment changes around an embedded system. For this reason, an application implementation needs to have several prototypes with different performance levels in order to address the environment evolution. This paper gives an approach for rapid embedded system prototyping using a generic high level architectural model and existing prototyping platforms. A several architecture prototype are proposed to rapid converge to a limed architecture space solutions, thus the exploration process is accelerated and an efficient solution can be selected.
