Avionics software is embedded software with legally mandated safety and reliability concerns used in avionics.The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety.
Processes are intended to support the objectives, according to the software level (A through D—Level E was outside the purview of DO-178B). Processes are described as abstract areas of work in DO-178B, and it is up to the planners of a real project to define and document the specifics of how a process will be carried out.
The Software Level, also known as the Development Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [10]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The ...
IMA modularity simplifies the development process of avionics software: . As the structure of the modules network is unified, it is mandatory to use a common API to access the hardware and network resources, thus simplifying the hardware and software integration.
AADL was first developed in the field of avionics, and was known formerly as the Avionics Architecture Description Language. [2] It was funded in part by the Army. The Architecture Analysis & Design Language is derived from MetaH, an architecture description language made by the Advanced Technology Center of Honeywell .
Model-based design provides an efficient approach for establishing a common framework for communication throughout the design process while supporting the development cycle . In model-based design of control systems, development is manifested in these four steps: modeling a plant, analyzing and synthesizing a controller for the plant,
ARINC 653 (Avionics Application Software Standard Interface) is a software specification for space and time partitioning in safety-critical avionics real-time operating systems (RTOS). It allows the hosting of multiple applications of different software levels on the same hardware in the context of an Integrated Modular Avionics architecture.
