Model of the ADA Avionics Real-Time System: An Example of the Benefits of theHardware/Software Codesign Approach in Development of Real-Time Systems

摘要

The Ada Avionics Real-Tim System (AARTS) Operating System (AOS) is the OS andmanagement system under development for the PAVE PILLAR architecture. The AOS, in its current version, was modeled in the Architectural Design and Assessment Systems (ADAS) along with the hardware and applications being exercised in the Avionics Directorate's Integrated test bed. The report describes the model, the results of simulation executions, and methods for expansion of the model to architectures larger than that of the integrated test bed.
