The time relativity and interactive property with the environment of a real-time system make the real-time software development very difficult. If in the case of multiprocessor environments the development work will be more difficult. In order to simplify the concurrent programming in the multiprocessor environment and reduce errors in the programming, the paper introduces a programming approach for the multi-processor system along with the software developing and enacting environment under this method. The method supports multiprocessor system software developing based on a visible graph mode (i.e. Object Oriented Petri Net) with witch the software can be developed efficiently and the reliable software can be obtained.
