An Automatic Code Generation Method Based on Directed Graph with Labels

Space TT&C system is in charge of the measurement and control of spacecraft and other TT&C objects. Due to the access of new target, the program of data processing needs to be developed incrementally. The TDRS software system is a Space TT&C system developed incrementally, which means that the basic functions are completed in the initial development and the software maintains continuous development to cope with the new target access. In this process, most of the software functions can be implemented by parameter configuration. However, the data processing function needs the software redevelopment. This paper presents an automatic code generation method based on directed graph with labels. This method guides the programmer to focus on the business logic modeling and generate the data processing code automatically. An example shows that this method can be applied in the TDRS system data processing and improve the software development efficiency and software quality remarkably.
