The general-purpose platform of one embodiment of the present of invention adopts the C language development, utilize professional platform independence, extensibility, high maintenance realization top box of digital machine applied software development, test and the maintenance process of middleware Technology to break away from concrete platform fully, reduce the cycle of top box of digital machine applied software development, improve top box of digital machine research and development of products efficient, reduce the cost of top box of digital machine product.The final products of one embodiment of the present of invention are based on integrated exploitation of top box of digital machine application software and the test environment of VC++.By the standard interface that uses a group to register and provide through the middle layer, the developer can finish exploitation, test and the maintenance work of top box of digital machine application software under the WINDOWS environment.
UML is OO powerful modeling synthetic language.Outstanding feature is to analyze the system that develops with designing institute with OO viewpoint.And for digital TV set-top box, it is the real time embedded system of a complexity, is difficult to according to this it be made up.Consider this situation, in conjunction with the special development environment of NEC, so UML is expanded and customization at masterplate, constraint and assembly respectively.
Expansion is as follows with the customization main points:
1. masterplate: the SDK that is defaulted as NEC;
2. constraint: strengthen constraint condition to real-time, concurrency, asynchronous communication and synchronous communication;
3. assembly: acquiescence is added the winGAI assembly;
And on this basis, can be according to the c language codes of the automatic generation of model with its semantic consistency.
Succeeding in developing of the modeling tool that generates based on UML and automatic code.By reasonably carrying out progress monitoring and quality management, reduced risk, the cost of software to a certain extent again, and the construction cycle that shortens software.
MVC (Model-View-Controller) is a kind of present pandemic software design pattern.Realize architecture based on most these patterns that adopt of the WEB application system under the J2EE platform.It is separated into model, view, three relatively independent parts of control to user-interface design, helps software transplanting and secondary development more.
Digital TV set-top box is compared with the WEB application system as a typical real time embedded system, has many singularity and complicacy.So the software design pattern of MVC has not only inherited but also developed to the software systems of the embodiment of the invention in conjunction with oneself factor.Wherein on the view layer, adopt the innovative technology Skin of user interface to change skin, do not need the update routine code just can offer the more personalized interface of user.
Embodiments of the invention have improved the embedded graphic user interface engine winGAI of facing assembly in interface prototype design and logic control.
Fig. 4 shows software development flow figure according to an embodiment of the invention, at first realizes this system and operation with the C language under the WIN32 environment; Second step, be transplanted to embedded platform and operation, and integrated third party's integration module; The 3rd step is based on the embedded software system development platform (analog simulation of UML visual modeling and the generation of robotization C language codes; And it is can generate the C code automatically, and irrelevant) with concrete embedded platform; In the 4th step, the application migration of utilizing this embedded software system development platform to generate automatically also realizes operation to embedded platform.
Fig. 5 shows according to embedded software system development process figure among Fig. 4, at first designs the pairing graphical symbol of control; Second step, the design database system; The 3rd step, design visualized graphs symbol modeling; The 4th step, design application interface generation system; The 5th step, design Add-In system; The 6th step, design C code generating system; The 7th step, the design and simulation system; The 8th step, the design cooperative operation system.
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, carry out by calculation element thereby they can be stored in the memory storage, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
