【Abstract】 The soft architecture framework is proposed,which is combined by a modular design method and parallel processing software technology based on the characteristics of open numerical controlled system.In this architecture,the time-sharing technology of resources is solved by cycle of rotation and interrupt priority method and the priority preemptive scheduling mechanism is adopted by the water treatment technology.Furthermore,Multi-CPU system hardware structure is used in this architecture.更多还原
