Research Of The Related Techniques In Integrated Avionics And The Design Of The Display Control Subsystem

Along with the fast development of aviatic technique and calculator technique,anew generation avionics system develops towards the direction of modularization andsynthesis. It has stridden into the stage of Integrated Modular Avionics(IMA). The IMAputs forward higher request to the software system.The ARINC653is a softwareinterface according to the standard in the avionics system. The characteristics of theARINC653is to define an general application excute(APEX) interface,which is exsitedbetween the operate system and the apply software. The apply software can complete itsprocessing by transferring the API through the interface. So the criterion can realizetransplant and reliability of the software,and satisfy the request of software in IMA.This thesis researchs the characteristic of the system structure and the requirementof the IMA and software structure of the partition Operation System that based onARINC653software criterion. It uses the example of the software design in the displayand control subsystem to introduce the step of software design,and to show the practicalvalue of ARINC653Partition Operation System in IMA. The main contents is:1. The software system requirements is proposed according to the characteristic ofarchitecture in IMA.The application software running on the same processor can notinfluence each other,so the operating system in IMA system must to isolate this effect..2. The development method of software in ARINC653partition operating system isproposed. The development method is different from the traditional non partitionoperating system. The development process of the software is the following: analysis ofsystem resource requirements, application design of the system software, and theIntegrate test of the system software.3. The development process of the software which based on the ARINC653partition operating system in the display and control subsystem is proposed. Itintroduces the function of the display and control subsystem in avionics. According tothe development process of the software,it completes the requirement analysis fordisplay and control subsystem, the software design and the system function test.
