摘要

操作系统(OS)应用程序编程接口(api)是在底层硬件发生变化时从软件角度实现独立软件和无缝升级的关键因素。这是使用开放系统所承诺的显著降低成本的机制之一。本文讨论了IEEE可移植操作系统接口(POSIX)和SAE AS5B2操作系统API工作组正在进行的工作，旨在为实时航空电子系统提供合适的操作系统API。本文还描述了操作系统API如何成为目标独立软件故事的重要组成部分，以及它如何与SAE正在开发的通用开放航空电子体系结构模型相适应。POSIX讨论总结了POSIX中正在发生的事情，特别关注实时工作组。大多数注意力被给予在P1003.21实时分布式系统通信中发生的活动。

Operating system application programmer interfaces (API) and their role in open systems for avionics

Operating System (OS) application programmer interfaces (APIs) are a key enabler to target independent software and seamless upgrading from the software perspective when the underlying hardware is changed. This is one of the significant cost reduction mechanisms promised by the use of open systems. This paper discusses on-going work within IEEE Portable Operating Systems Interfaces (POSIX) and SAE AS5B2 Operating System API working group that address providing a suitable OS API for real-time avionic systems. This paper also describes how the OS API is a significant part of the target independent software story and how it fits in with the generic open avionics architecture model being developed by the SAE. The POSIX discussions summarize what has been going on in POSIX, with particular attention to the real-time working groups. Most attention is given to activities occurring in P1003.21 Real-Time Distributed Systems Communications.
