An Automatic Development Process for Integrated Modular Avionics Software
With the ever-growing avionics functions, the modern avionics architecture is evolving from traditional federated architecture to Integrated Modular Avionics (IMA). ARINC653 is a major industry standard to support partitioning concept introduced in IMA to achieve security isolation between avionics functions with different criticalities. To decrease the complexity and improve the reliability of...
متن کاملSafety-Critical Software Development for Integrated Modular Avionics
Many avionics systems have been successfully developed using custom hardware and software. However, in recent years, the full life-cycle costs of customized systems have forced original equipment manufacturers (OEMs) to consider the use of COTS-based systems. At the same time, there has been a noticeable migration away from federated architectures, where each individual subsystem performs a ded...
متن کاملScheduling in Dependable Integrated Modular Avionics
In the recent development of avionics systems, Integrated Modular Avionics (IMA) is advocated for next generation architecture that needs integration of mixedcriticality real-time applications. These integrated applications meet their own timing constraints while sharing avionics computer resources. To guarantee timing constraints and dependability of each application, an IMA-based system is eq...
متن کاملSafety Assurance Contracts for Integrated Modular Avionics
This paper describes a method for performing safety analysis on an Integrated Modular Avionics system in a manner which supports the incremental development and change of system components. This is achieved by analysing each component in the context of the overall system design and then finding derived safety requirements. Each IMA component (hardware, software or both) is then examined to dete...
متن کاملAn Approach for Supporting Temporal Partitioning and Software Reuse in Integrated Modular Avionics
The Integrated Modular Avionics (IMA) approach can achieve lower overall hardware costs and reduced level of spares by getting multiple applications that have traditionally been implemented using separate, federated units to share hardware resources. However, the IMA approach also brings new challenges that did not exist in the federated setup. Avoiding unwanted dependencies among applications ...
