Abstract


With the continuous development of information technology , the real-time system has penetrated into all areas of life , such as process control , agile manufacturing , nuclear reactors , aerospace and other fields , it plays a very important role . The results of the real-time output of the system is correct or not, depends not only on the result of the calculation of the system , and also whether the system within a predetermined time range of the calculated results for . This feature is significant signs of the real-time system is different from other systems , and also the difficulty of the development of real-time systems . However , this feature is essentially not functional characteristics , it is just a non-functional concerns , and to crosscut other core functions concerns . Concerns of the functional and non-functional concerns are mixed together , leading to the high complexity of the software design , and not conducive reuse and maintenance , it is difficult to effectively ensure the system's real-time , security, and reliability . The traditional approach to software development can not be an effective solution to this problem. Aspect-oriented programming is a good solution to the code level crosscutting concerns in the field of application software has been very good for industrial applications . Therefore , this paper presents the development of aspect-oriented ideas for real - time system development process . Aspect-oriented software development has been very mature in the code to achieve the level of language , but in a higher level of development , lack of support , for example in the design level , it is the lack of good modeling mechanism . To aspect-oriented thinking application in the development of real-time systems , should be provided throughout the development process support, and not just stay the implementation level . Therefore , this paper proposed a UML-based aspect-oriented modeling approach . UML lightweight extension mechanism supported by the language in the existing UML modeling tools . By analyzing the characteristics of real-time systems in real-time , real-time characteristics of different types , and different mechanisms of aspect-oriented programming realization . Finally, through specific case to demonstrate the aspect-oriented real-time system development process .
