Description
Technical Field
The invention belongs to the technical field of embedded software development, and particularly relates to an embedded software modular design method.
Background
With the development of computer technology and the wide application of software, the proportion of embedded software in armored vehicles is increasing, and the scale and complexity of the embedded software are increasing. Embedded software has become a core part of armored vehicles and software quality issues have become bottlenecks in the quality of armored vehicles. However, the functions and the layers of embedded software in the existing armored vehicle system are not clearly divided, and the association degree of an application layer and a hardware platform is too high, so that the transplanting difficulty of the embedded software among different platforms is high, and the development period is long.
The embedded software development technology mainly comprises a structuring method, an object-oriented method and a modularization method. The structured method emphasizes process abstraction and function modularization, is one of the most mature and widely applied software development methods, but is very sensitive to system functions, often needs redesign when the functions are changed, and is poor in transportability. The object-oriented development method overcomes the difficulty of structuralization, and has the advantages of simple maintenance, high portability and high integration. The object-oriented development method reuses source code level, and the software is difficult to realize at present when being produced on a production line like hardware and assembled into an embedded system software like a shelf product.
