Embedded Applications Based On Deltacorba Design Simulation Environment

Nowaday, the embeded system is applied more and more extensively.When the user designs the embeded application system,the real time capability will be cared by the user.It is one of the important aspects about quality of software.In the software system, the division of tasks and modules, the setting of task priority,the arithmetic design,the calculating time of different modules and communications mechanism among the tasks will affect the real time capability of the embeded application system.So to ensure the quality of software,the real time capability must been cared from the beginning of requirment analyse ."Emulating environment of design of embeded application system" will help the application developer to analyse execution flow and real time capability, finding unreasonable places which can be modified in time. CORBA offers the interfaces and modules independent of platform for object oritented ,distributing application program.Many users use CORBA to develop the embeded application system.DeltaCORBA developed by Coretek company is based on miniCORBA standard .It is embeded CORBA whick supports some embeded operating system ,such as DeltaOS,Tornado. At the same time,this emulating environment offers the resolving scheme about developing embeded application system based on DeltaCORBA. This paper is based on a implementation of an emulating environment of design of embeded application system.,which was realized by the Coretek company that the author participated in.In this paper , DeltaOS and DeltaCORBA developed by Coretek company are introduced at first,then the design and implementation solution of this emulating environment are introduced.At last ,the author sets forth the ideas for the future improvement and sum up this paper.
